DOXA L/M pumps
API 675 plunger and double diaphragm metering process pumps, designed to assure the greatest reliability in heavy duties:
- manufactured according to API 675 Std., “non lost-motion” type construction;
- continuous adjustment of capacity (plunger stroke from 0 up to 25mm), from 0 to 100% while the pump is at rest or in operation;
- metering accuracy better than 1% over the normal operating range from 10 to 100% of capacity;
- patented capacity adjustment system, with mechanical plunger return stroke;
- completely enclosed crankcase made of cast iron;
- groupable in multiplex units, also with pumps of different series;
- two series available:
- DOXA.L with max allowable thrust 2.000 N (design 2.500 N);
- DOXA.M with max allowable thrust 7.000 N (design 9.000 N);
- double diaphragm sandwich type arrangement available (diaphragms hydraulically actuated by means of an hydraulic circuit with relief and refilling valves);
- PTFE or metal diaphragms, with facility for local or remote diaphragm leakage detectors;
- two types of diaphragm liquid ends:
- type DS – PTFE double diaphragm sandwich type, i.e. with an oil film between the diaphragms;
- type MM – metal double diaphragm sandwich type, mainly used for low capacity and high pressure and temperature services;
- continuous stroke adjustment, manual or automatic, with pump at rest or in operation; linear adjustment scale with local reading display.
