Hydra-Cell® Metering Solutions P400 Pumps offer enhanced performance
Wanner has made significant improvements to its Hydra-Cell Metering Solutions Model P400 pumps that aid in priming for low-speed operation and improve performance when pumping gaseous fluids such as hypochlorite solutions. Geometry changes to the diaphragm pocket valve plate have reduced the diaphragm pocket by 30%, thus minimizing “dead space” within the pump chamber. In addition, the valve port through-holes have been reduced by 6% to increase fluid velocity through the valve plate.
Used for a wide range of metering applications in chemical processing plants, the Hydra-Cell P400’s multi-diaphragm design provides a virtually pulse-free flow without the use of expensive pulsation dampeners. It exceeds API 675 performance standards for steady-state accuracy (±1%), linearity (±3%) and repeatability (±3%).
This Hydra-Cell P400 with a reduced pocket valve plate has a flow capacity of 766 l/hr (202.36 US gal/hr) and a maximum pressure of 69 bar (1000 psi) for metallic pump heads and 24 bar (350 psi) for non-metallic pump heads. Wanner 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, disk check valves, combines with the seal-less design, enable model P400 pumps to handle viscous fluids and abrasive particulates up to 500 microns in size. These pumps can also run dry indefinitely without damage to the pump and are 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) is available to help provide a complete chemical-feed pumping system.
