CheckPoint's Series MDZ pump delivers up to 60 USG/H (227 L/H) and can reliably inject into pressures up to 1,500 PSIG (103 BARG). The Series MDZ features a unique drive system which efficiently converts the rotational energy of the motor to axial energy and pressurizes hydraulic oil, actuating a single nonmetallic diaphragm. The process pressure is constantly balanced by hydraulic pressure on its opposing side so the flexible diaphragm essentially experiences zero differential pressure - enabling incredibly low diaphragm failure rates.
