Dencil Pumps offer manufacture a range of diaphragm pumps high pressure pumps and chemical metering pumps. Where leakage is not at all permitted dDiaphragm pumps are advisedrecommended for hazardous, toxic and poisonous liquids, where leakage is not at all permitted. These diaphragm pumpsy have hydraulically actuated diaphragms and back pressure valves, the main function of a back pressure valve being to balance the hydraulic oil in the oil chamber. The reciprocating plunger of pumps transmits displacement through hydraulic oil to the diaphragm, the oscillation of which generates produces pumping action on process fluid. The diaphragm acts as a perfect seal between the hydraulic oil and the liquid being pumped. These diaphragm pumps can be supplied provided with single or double diaphragm and . uUsually teflon acts as a diaphragm. Double diaphragm with double acting valve is suitable Ffor slurry or hot liquids, double diaphragm with double acting valve is suitable. The diaphragm pumps can be manufactured offered in capacities up to 6000 ltr/hr and pressure ratings up to 10 kg/cm2. The back pressure valve which is in the hydraulic oil tank, there is a back pressure valve which ensures pumping accuracies for long period.Due to oil leakage, tThe pressure drop in hydraulic chamber due to oil leakage is automatically compensated by opening of the back pressure valve. Besides, Iit acts as a safegaurd from damages if discharge pressure exceeds pump rated pressure.
