Encore® 700 Diaphragm Metering Pump

"encore<sup® 700″/>

A rugged, heavy-duty mechanical diaphragm metering pump available with
six diaphragm sizes and simplex, duplex and double simplex

The Encore® 700 pump is engineered to handle industrial
and municipal metering applications in water and wastewater treatment,
swimming pools, food processing, chemical processing, brewing and
distillation, and agriculture.

 Configuration Options
 Simplex Pump Offers single head design on single gear box with stroke control.
 Duplex Pump Offers two identical sized heads on single gear box with common stroke length control, and a direct drive arrangement.
 Double Simplex Offers two heads with two gear boxes each with independent stroke length control, and a common motor.


Combines robustness of hydraulic diaphragm drives with the
unparalleled economy, simplicity and serviceability of mechanical
diaphragm liquid ends.
Handles capacities to 634 gph (2,400 l/h), back pressures to 175 psi (12
Non-loss-motion (amplitude modulation) stroke adjust mechanism renders
unrivaled efficiency, longevity and reliability.
Choice of two field convertible drives-direct coupled or pulley coupled.
Precision engineered liquid ends meter mild solutions, aggressive
chemicals, high viscosity polymers and slurries with far greater
efficiency than conventional liquid ends.
Clear PVC cartridge valves for fast, fool proof service with no piping
disturbances and built-in visual indication of operation.
Premium diaphragm design ensures high metering accuracy, even at varying
discharge pressures.


Efficient, reliable and smooth discharge pattern through the use of a variable non- loss-motion eccentric stroke adjustment
High metering accuracy even at varying discharge pressures
Choice of direct coupled or pulley driven, for an additional 4:1 turndown on stroke frequency
Fast and easy service of valve assemblies without disturbing the suction and discharge piping
Visual indication of operation with standard clear PVC valves housing
Choice of configurations:- simplex, duplex and double simplex.
