Wanner Engineering Introduces New Hydra-Cell P700 “Pulse-free” Metering Pump

By: Wanner

Wanner Engineering, Inc., Minneapolis, Minnesota (USA), announces the introduction of its new Hydra-Cell Metering Solutions P700 Series metering pumps. They feature a hydraulically balanced, multiple-diaphragm design to provide smooth, linear, virtually pulse-free flow without the need for expensive pulsation dampeners. Employing Variable Frequency Drive (VFD) electronic flow control adjustment, P700 metering pumps deliver precise, accurate flow throughout the turndown range at up to 1394 gph (4396 lph) with discharge pressure ratings to 1200 psi (83 bar), Wanner Engineering states.

As part of the extensive line of Hydra-Cell seal-less pumps, the P700 features patented diaphragm position control that protects the pump and enables operation in case of a closed inlet. Since the process fluid is not used for lubrication, the P700 can run dry indefinitely. According to the company, a replenishment valve in every piston assembly ensures optimum actuating oil on every stroke for continuous accuracy.

New Hydra-Cell P700 metering pumps are available in a choice of Brass, Ductile Iron, Duplex Alloy 2205, 316L Stainless Steel, and Hastelloy C pump head materials. The 316L Stainless Steel heads can be fitted with ANSI flanges or SAE flanged ports. Several diaphragm and check valve materials of construction allow the P700 to be used in a wide range of processing and other metering applications. The check valve orientation and seal-less design enable the P700 to handle abrasive particulates up to 800 microns in size, Wanner Engineering states.

A variety of options and accessories (e.g., pressure valves, calibration cylinders, motors, and controllers) are available with the new model P700 to provide a complete metering pump system. This includes the “Control Freak” touch-screen metering controller with built-in programming to provide motor speed control for Hydra-Cell Metering Solutions pumps.
