The unique high pressure characteristics of the MTH
regenerative turbine pumps make them ideal for pressure injection applications.
One application is to inject creosote at 150 psi into wooden poles and
bridge planks to preserve the wood and prevent insects and animals from
eating the wood.
Another type of pressure injection is the adding of chlorine to water
treatment systems. In this application, a relatively small amount of water
(generally, less than 30 GPM) is diverted from the main stream to an MTH
pump, which provides the high pressure required to force the water through
a special orifice which creates a vacuum that pulls chlorine into the
system and mixes it into the main water line.
Yet another application injects curing agents into concrete. The high
pressure of a regenerative turbine is used to drive the curing chemicals
through nozzles, while the low flow characteristic provides metering control.
These agents control the drying time and are varied depending upon the
travel time to the job, as well as environmental conditions.
