Heavy-duty industrial pumps for the processing industries, car wash facilities, plus OEM, and agricultural and landscaping applications. Hydra-Cell positive displacement pumps feature a sealless pumping chamber and hydraulically-balanced diaphragm design, enabling the pumps to provide leak-free, low-maintenance performance while processing difficult fluids over a wide range of pressures and flows. Hydra-Cell pumps can run dry without damage and will handle abrasives and particulates (up to 500 microns) that can destroy other pumps. Multiple dia- phragms minimize pulsations, so Hydra-Cell operates virtually pulse-free, often eliminating the need for expensive pulsation dampeners.
