Steep Operating Characteristics
Near-constant capacity is maintained over wide variations in pressure. High shut-off pressure overcomes temporary line resistance.
A hydrodynamic film on each side of the impeller positions it for long life. The impeller exerts no thrust load on bearings. Pump operates equally well in a vertical or horizontal position.
Bronze fitted pumps have Buna N elastomers, high temperature carbon, and ceramic seats for best hot water service. Optional seats and materials are also available.
300# Case Working Pressure
Rigid structure is designed for maximum casing strength.
Volatile Fluid Handling
Turbine impeller handles vapors in excess of 20% by volume, minimizing the possibility of vapor locks.
“O”ring seals are used throughout the 7DT7 Series pumps to assure sealing and ease of service.
