Steep Head/Capacity Curve
Pumping capacity varies only slightly as pressure changes. Steep
pressure characteristic overcomes temporary line resistances.
Self Adjusting Impeller
140/180 Series impellers utilize balancing holes to promote hydraulic
self-centering and to elimanate the need for external adjustment.
The impeller exerts no thrust load on the bearings, thereby extending
400# Case Working Pressure
Rigid structure is designed for maximum casing stregth.
Every pump is fully tested to verify performance prior to shipment.
Volitile Fluid Handling
The turbine impeller handles vapors up to 20% by volume, minimizing
the possibility of vapor lock.
Bronze fitted pumps have EPR rubber, high temperature carbon and
ceramic seats for best hot water service. Optional seats and materials
“O” Ring Gaskets
“O” ring seals are used throughout the 140/180 Series
pumps to assure positive sealing.
Pump shaft is high strength 416 stainless steel material.
Heavy duty sealed ball bearings on inboard and outboard ends of
the shaft are permanently lubricated for maintenance free service.
Water flingers provide added protection to ball bearings in the
event of seal leakage.
New pump designs optimize efficiency for each size available.
140/180 Series pumps may be operated under adverse inlet conditions
without audible or measurable cavitation.
New inlet design provides supior fluid handling ability with low
head inlet condition.
