Hydra-Cell pumps offer the benefits of both diaphragm and plunger pumps without the drawbacks, says Wanner International.
The placing of multiple diaphragms in a single pump head is designed to ensure the volumetric accuracy of a conventional metering pump, but with very low pulsation, removing the need for pulsation dampeners in many instances.
Hydra-Cell pumps are also more economical than traditional diaphragm metering pumps, says the company, in terms of acquisition, spare parts and energy costs.
At a given flow and pressure, a traditional diaphragm pump with a 15kW motor can usually be replaced with a Hydra-Cell metering pump with a 5kW motor. Thanks to a compact footprint, a Hydra-Cell can also free up valuable real estate – so critical in many applications.
Unlike plunger pumps, Hydra-Cells have no dynamic seals and offer 100% containment of the pumped liquid.
They have no seals through which hazardous fluids might escape or through which air could enter the system on the suction stroke to cause degradation or crystallisation of the pumped liquid.
Meeting or exceeding the performance requirements of API 675, and available with ATEX approval, Hydra-Cell pumps are becoming a popular choice in metering and dosing.
