Manufacturer supplier exporter of the piston vacuum pump.

The DEP series is a 100% oil-free piston vacuum pump. They are designed for continuous operation from atmospheric pressure to the pump’s ultimate vacuum levels of 27.5 inches of mercury (DRPS) and 29.5 inches of mercury (DRPC). They are ideal for applications where oil-sealed or water-sealed pumps are not suitable.

These units come with a motor (with thermal protector), vacuum gauge, hose connectors, exhaust muffler/muffler, support legs, and a heavy-duty 6ft long 120v (15A) power cord. Specifically designed for pumping air and other non-reactive, non-corrosive, non-flammable gases.

Applications include medical, dental, biofiltration, chip mounting/fixing, air sampling, vacuum packaging, material handling, environmental equipment, and more.

Advantages of Piston Vacuum Pumps

Piston vacuum pumps have many advantages. First, they can contain water with high density and vapor pressure. As you probably already know, a piston compresses a liquid and turns it into steam when its pressure falls below the flash pressure. This process consumes up to half the pumping speed and limits its performance. Fortunately, piston pumps are easy to rebuild. A qualified technician can restore pump performance within 15 to 1 hour.
Piston vacuum pumps are used in a variety of scientific and industrial applications. In particular, they can be used to make CRTs, lamps and vacuum tubes. In addition, they are used in various mechanical equipment. Motor vehicles often use these pumps to power hydraulic components. Likewise, airplanes use them to control gyroscopes.
Piston vacuum pumps are also used in printing equipment. These pumps have many uses in the printing industry, including ink degassers and vacuum packaging machines. In addition to this, they can also be used in screen printing machines and photographic platesetters. Other applications for vacuum pumps include buried machines, ovens, and plasma cutting equipment.
Oil-free piston pumps are popular for a number of reasons, including that they don’t require any lubricant and don’t create contaminants. These properties make them particularly suitable for use in enclosed rooms, laboratories and cleanrooms. Additionally, they are lightweight, durable in design and easy to maintain.

One of the key elements of a vacuum pump is atmospheric pressure, which is the weight of the air pressed against the earth. This pressure is created by the reduced weight of air molecules at higher altitudes. Air pressure or atmospheric pressure has a significant effect on the operation of the machine, especially the operation of the vacuum pump. The pressure is always trying to equalize as molecules move from high to low to fill space, a process based on the idea that pushes the molecules.
