Plunger Metering Pump

Encore® 700

Precise Metering, Robust and Reliable

The Encore® 700 plunger pump is a simple to use plunger pump built for heavy duty conditions and longevity. Metering accuracy is achieved by a carefully designed liquid end which enables a full 10:1 turndown within +/- 1% flow repeatable accuracy.

It is available in Simplex, Duplex and Double Simplex configurations, the latter providing an independent liquid adjustment of both liquid end outputs.

Unlike solenoid or loss motion pumps, the Encore® 700 plunger pump is driven by a rotating crankshaft, where the eccentricity can be smoothly adjusted during operation. There are no return springs, the diaphragm moves with a simple harmonic motion. The fluid velocity profile is sinusoidal at all stroke lengths; adjusting stroke length simply alters the amplitude of the sine wave. This design provides reliability and longevity and pump valves operate with far greater efficiency and minimal system vibration.

  • Efficient, reliable and smooth discharge pattern through the use of variable non-loss motion eccentric stroke adjustment

  • High metering accuracy even at varying discharge pressures

  • Choice of direct coupled or pulley driven to suit the environment and market place

  • Fast and easy service of valve assemblies without disturbing the suction and discharge piping

Configurations to suit the complexity of the application /site layout restrictions

Simplex Pump

Offers single head design on single gear box with stroke control

Duplex Pump

Offers two identical sized heads on a single gear box with common stroke length control and direct drive management.

Double Simplex
