Wanner Engineering Hydra-Cell Metering Solutions P400 Pumps Decrease Risk Of Pump Pack-Out And Vapor Lock

Wanner Engineering, Inc. announces a significant improvement to its Hydra-Cell Metering Solutions Model P400 pumps. Geometry changes to the diaphragm pocket valve plate have reduced the pocket by 30%, thus minimizing “dead space.” This decreases the risk of pump pack-out and vapor lock, aids in priming for low-speed operation and improves performance in gaseous fluid applications. In addition, the valve port through-holes have been reduced by 6% to increase fluid velocity through the plate, according to the company.

Also featuring a multiple-diaphragm design to provide virtually pulse-free flow without the use of expensive pulsation dampeners, the P400 is used for a wide range of metering applications in chemical processing plants. It exceeds API 675 performance standards for steady-state accuracy (±1%), linearity (±3%) and repeatability (±3%), according to the company.

The new Hydra-Cell P400 with a reduced pocket valve plate has a flow capacity of 242.8 gph and a maximum pressure of 1000 psi (69 bar) for metallic pump heads and 350 psi (24 bar) for non-metallic pump heads. Wanner Engineering says that the seal-less design of Hydra-Cell means that there are no dynamic or mechanical seals, cups or packing to leak, wear or replace.

Spring-loaded, horizontal disk check valves and the seal-less design enable model P400 pumps to handle viscous fluids and abrasive particulates up to 500 microns in size. The P400 can also run dry indefinitely without damage to the pump and is available in a wide choice of pump head, valve, diaphragm and o-ring materials. A variety of options and accessories (e.g. pressure regulating valves, motors and controllers) are available to help provide a complete chemical-feed pumping system.
