PSG TECHNOLOGIES - FOUR PISTON DIAPHRAGM PUMPS:
PSG’s electrically driven four-diaphragm pumps are designed to convey extremely delicate biologically active molecules, similar to the human heart. Who knew a couple of million years of evolution developed the perfect device (the heart) to pump blood that contains albumin, gamma globulins, clotting factors and cells. Using similar technology, we’ve closely duplicated the principals of operation for the heart, to create a pump that features variable flow, accurate dosing, sanitary properties, and energy efficient, with long life.
Inside our four-diaphragm pumps, a variable motor turns an eccentric shaft that drives pistons to operate each of the individual diaphragms, while check valves ensure accurate volumetric efficiency. These four piston-diaphragm, positive displacement pumps, are suitable for use in multiple and single-use applications within the pharmaceutical and biotech industries. When pharmaceutical companies need low shear, low slip and low pulsation to pump biological organisms in aqueous suspension through specialized filtration equipment, they turn to PSG.
