Design Features

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 service life.

400# Case Working Pressure

Rigid structure is designed for maximum casing stregth.

100% Tested

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.

Mechanical Seals

Bronze fitted pumps have EPR rubber, high temperature carbon and ceramic seats for best hot water service. Optional seats and materials are availible.

“O” Ring Gaskets

“O” ring seals are used throughout the 140/180 Series pumps to assure positive sealing.

Shaft

Pump shaft is high strength 416 stainless steel material.

Bearings

Heavy duty sealed ball bearings on inboard and outboard ends of the shaft are permanently lubricated for maintenance free service.

Water Flingers

Water flingers provide added protection to ball bearings in the event of seal leakage.

Best Eficiency

New pump designs optimize efficiency for each size available.

Non-Cavitating

140/180 Series pumps may be operated under adverse inlet conditions without audible or measurable cavitation.

Low NPSH

New inlet design provides supior fluid handling ability with low head inlet condition.
