EV-N Flow

Constant Flow Metering for the EV-1 Metering Pump

The EV-N Flow option for the EV-1 metering pump features a unique linear flow that eliminates the need for pulsation dampeners and replaces maintenance-intensive gear pumps. Even-flow, pulse-less metering is accomplished through a dual-feed design utilizing two identical feeds and a programmed cam for smart plunger control. Other features include:

• Dual-feed unit delivering up to 220 gph (833 l/h) per drivecase of smooth flow metering for either suction or discharge. Provides the accuracy of a metering pump without the concern of reciprocating flow patterns.
• Linear flow control to 10:1 turn down ratio via standard variable speed drive packages for superior process control.
• Multi-fluid handling capabilities with sealless design, suitable for viscous and corrosive fluids and abrasive slurries to 250°F (121°C).
• Programmed Cam to provide overlapping flow pattern, reduce check valve transition and keep pump flow proportional to motor speed.
• Reduces pipe strain.

Note: Inverter duty motor is required.
