Product's Features

Capacity : 15Lpm to 75 Lpm

Minivac SV Series Diaphragm Pumps are completely oil free & motor mounted.

These vacuum pumps are available in the range of 15 Lpm to 75 Lpm with a maximum vacuum of 27" Hg & pressure of 60 Psig. The choice of series & parallel connection in double-stage models gives selective advantage of flow & vacuum / pressure.

They are extremely light weighted due to die cast aluminum construction.

Can be offered with Tephlon coated or PP wetted parts for chemical resistant applications, chemical resistant models are supplied with flameproof electric motor.

Available with special diaphragm option (Tephlon coated, Viton etc.)

These are useful for various applications like Pollution control equipment's, Laboratories, Flame photometer, plastic welding machines, agitation of chemicals, aeration, oil spray painting etc.

Principle Working

Diaphragm vacuum pumps operate based on the principle of reciprocating motion, utilizing a flexible diaphragm to create vacuum or pressure. The diaphragm is driven by an electromagnet or a motorized mechanism, leading to its reciprocating movement. During the suction stroke, the diaphragm moves downward, enlarging the pump chamber and drawing in gas or air from the inlet.

As the diaphragm moves upwards during the compression stroke, the pump chamber reduces in size, forcing the gas or air out through the outlet. The cycle repeats continuously, resulting in a smooth and pulsation-free flow. Diaphragm vacuum pumps are characterized by their oil-free operation, ensuring clean and uncontaminated vacuum generation.
