In-house Capabilities

MTH Pumps In-house capabilities include:

• Philosophy

Since its inception, it has been the goal of MTH to custom design and develop pumping products to fit applications in which they are the technically correct pump solution. Recognizing the fact that no other U.S. pump manufacturer had adopted this strategy, MTH acquired the resources needed to bring it to the leading edge of pump product design and development. When it comes to developing products that provide solutions for the ever-changing pumping requirements faced by industry today, MTH is at the forefront. Our desire to maintain this advantage has promoted a mindset of continuously investing in state of the art design, development, and manufacturing equipment capable of providing our customers with the best possible product for their fluid handling requirements. This investment has proven highly beneficial for both MTH and its customers, because our customers receive pumping solutions specifically suited to their design requirements, and MTH has earned the reputation as a problem solver, which has translated into additional growth opportunities over the years.

Another important factor in MTH's continued success has been our philosophy of vertical integration. It was understood very early on that being in control of the entire product development cycle from design, to prototyping, to manufacturing, was the key to our ability to tightly control product cost while producing the most efficient design in the least amount of time. This control and coordination at all phases of product development adds a flexibility and agility to the company that distinguishes MTH substantially from other pump companies, and has provided us with the ability to react much more quickly to our customers' changing needs than our competitors.


MTH has experienced application engineers on staff who are always available to consult with your engineers to determine if a regenerative turbine, centrifugal, or other pump product is the proper selection for your application. We first attempt to learn enough about an application's mechanical and fluid requirements, such that we could almost literally redesign the customer's equipment. After all aspects of the system and application have been examined, and potential system improvements have been considered, a combination of standard and newly designed components are selected based upon the design requirements and economics of the situation. When MTH and the customer are comfortable with the direction of the pending proposal, a tentative design is prepared, including cost. If the preliminary design meets with customer approval, we then proceed to the design phase.

Design Capabilities

In addition to an excellent staff of design engineers, MTH has also retained the services of some highly experienced and successful pump designers that are utilized as necessary for special pump design projects. Using SDRC Master Series for 3D solid modeling design and drafting, new product designs are analyzed and processed concurrently with various departments to consider pattern and mold making needs, tooling, production machinery, assembly-testing equipment, packaging, and shipping methods.


MTH uses a variety of methods and procedures in the development of prototypes. We produce our own sand castings in our sister company, P&W Foundry, or purchase high accuracy investment castings from an outside foundry that we partner with to produce on short notice. To support these foundry operations, our design staff turns solid model design layouts directly into 3D pattern or mold designs. Molds for investment casting wax patterns, or patterns for the sand foundry are built directly from these 3D solid models via an advanced CAM system that feeds a dedicated computer controlled vertical machining center, located in our own tool room. MTH can then produce wax investment casting patterns with its own injection-molding machine, or instruct our foundry to produce one-off prototype green sand castings the same day. When time is critical or when the design is expected to evolve significantly prior to actual production, the investment casting wax patterns are produced on our own highly accurate rapid prototyping machine directly from our solid model part geometry without any dimensional losses or expensive tooling required.

Our own tool room/model shop manufactures other components and machines the castings as they arrive to build engineering models for testing. Before the design is finalized, our chief toolmaker and tool designers use these prototype components to determine the best manufacturing methods as well as the optimum tooling and holding equipment that will be required for production manufacturing.

Development Testing

After the engineering prototypes are assembled, they are tested to determine if they meet the performance requirements of the proposed design. They are then evaluated to ensure that they meet any other criteria that has been determined by MTH or the customer's engineer such as form or fit. Whenever possible, special testing fixtures or equipment are designed and built at the time of prototype testing, or in some instances the customer's own equipment is used to prove out the design. Manufacturing Engineering is at that time given the opportunity to analyze and create production assembly/test equipment designs for the product, in anticipation of full production status. MTBF or other testing is undertaken in accordance with the customer's request and definition of application operating limits and fluid characteristics. Customers are encouraged to supply production samples of their equipment along with the actual test fluids whenever possible, to provide the highest levels of certainty about the suitability and reliability of the product design to meet and exceed specified requirements.

Process Engineering/Cost Studies

Upon successful completion of the testing phase, final decisions are made for all first run production materials and methods. Often it is determined that production will begin using one material or method, with the understanding that another will be phased in at a later date as volumes ramp up. Production plans are made to evolve manufacturing methods towards lower cost, higher quality, and/or longer life of the product. These plans are implemented as advised by the engineers with design control approval (be it MTH or the customer). It is the policy of MTH to share volume cost savings with OEM customers as they are realized. Typically, at this point, MTH has gathered enough information to make the final proposal to the customer with the utmost confidence in both the performance and cost of the product.

Manufacturing Equipment and Facilities

MTH purchases and maintains the latest machinery to manufacture regenerative turbine, centrifugal, and other OEM pumps. Robotic loading, live tooling, multi-head lathes, and other state of the art multitasking manufacturing concepts are employed to help in the reduction of manufacturing costs and increasing part quality. In addition, all proposed manufacturing equipment and facilities are reviewed concurrently with new pump design to assure adequate capacity and capability. The addition of a bronze and aluminum green sand foundry, pattern/mold making shop, as well as a complete metal fabrication facility further extends our ability to control product quality, cost, and design features. As an example, during a manufacturing review of a new brazed-together vertical sealless pump design, it became apparent that the addition of a high volume production brazing machine would be advantageous in helping increase the quality and consistency of brazed joints, while reducing the overall cost of the unit. These reduced costs are allowing MTH to expand the use of this product into other applications, which is increasing volume, and lowering costs even further. This is a prime example of how the philosophies of vertical integration and concurrent engineering are driving the expansion of MTH in the pumping industry.


It has always been MTH's concept to assemble and then test 100% of our pump products before they leave the factory. In many instances we have developed specific testing procedures and certifications to meet the needs of our customers. All units meet written testing specifications or are rejected to our internal quality review system. While the goal of using standardized pump parts wherever technically appropriate, makes most new products easy to assemble and test using existing equipment, new products sometimes have required new facilities and procedures. For example, during the year 1999 and into 2000, an entirely new facility was purchased and refurbished, while new equipment was designed and built to manufacture, assemble, and test sealless canned motor pumps. The facility now has the capacity to produce 100 X Series pumps per week in its current configuration. Even now however, MTH is planning additional stations for new pump sizes and horsepower ratings in anticipation of the dramatic expansion of the X Series and other sealless pumps into many new applications in upcoming years. Each of the X Series units are currently tested using the customer's prescribed fluid, with the resulting test curve including power input, flow, and pressure recorded electronically by date and serial number. This rigorous testing procedure has proven to be quite effective, and helps attest to the reliability of these units which shows that out of over 800 X41's shipped into the field between 1997 and 2004, there have been zero reported problems.

Packaging and Shipping

Every new product is carefully reviewed once the appropriate design dimensions and handling limitations are known to determine the best packaging and shipping methods. Often special packaging is necessary to handle individual unit or bulk packaging requirements. MTH can engineer packaging to meet customer needs or employ the services of our custom packaging partner to design specialized solutions for domestic or overseas shipment.


Highly capable customer service is the norm at MTH. From the intelligent, quick response of its inside sales and engineering staff to the large stocked inventory capability that allows shipment of standard products in 3-5 days or less, MTH continuously strives to meet and exceed customer expectations. MTH also provides a variety of repair services to suit customer requirements. Exchange programs, field repair kits, detailed repair manuals, and some onsite services are also available for normal maintenance and servicing tasks. For more critical circumstances, we also offer various failure analysis services to suit the customer's individual needs. To proactively address potential customer service issues in the future, MTH continuously records and reports failure modes and root causes to determine areas to focus our internal quality improvement efforts on, whether the failures are product or application related.
