for chemicalswith electric motordouble-diaphragm

Sandwich Hydraulic Diaphragm Dosing pump MR I Sandwich Hydraulic diaphragm dosing pumps comply with mechanical and performance API 675 standards. Furthermore, they comply with ATEX standard, therefore they can be installed in hazardous area. Mechanism is an internal worm gear, fully oil bath lubricated with possibility to be coupled with others independently from the size and stroke number to obtain multi-heads unit. Stroke adjustment can be carried with the pump at rest or in operation and it can be manual or automatic through automatic actuator driven by 4-20 mA; different BUS; pneumatic. Accuracy within ± 1% within 10-100% of rated capacity. MR I pumps are equipped with mechanical replenishment, internal safety system to protect the pump from overpressure and suction line obstruction. The peculiarity of this pump is the special sandwich diaphragm and the reliability of the diaphragm rupture detection system. Wide choice of wetted materials: S.S.316L; PVC; PP; PVDF; PTFE; other materials available upon request.
