What is a duplex pump?

The duplex pump is a pump that usually occurs in the treatment of waste water and oil fields. It consists of two pumps that alternate the pumping process, allowing it more efficient than one version. The duplex pump has a higher flow because it does not have a dead pump. When one pump completes its stroke cycle, the other begins its thrust - maintains the maximum pumping effect without interrupting the cycle.

The first duplex pump was controlled by steam. It consisted of two steam chambers and two pump cases. The pumps were able to draw twice as much liquid as a one -stage pump. There are no dead places in the duplex pump. The pumping rollers are constantly under pressure and work to each other enough to ensure that one or the other is always pumped. The compressed air acts in the same way as Steam and maintains constant pressure on the pump cylinder. The original steam duplex pump was created in the 18th century and steam pumps are still used but compressedThe air took over as a primary operating system.

Duplex pump is used if a high volume of permanent pumping is required. Waste water pumps use pumps for the need to move large amounts of water without threatening reverse flushing. Any reverse flushing could potentially contaminate large freshwater storage tanks and make the system unsuitable for use.

In the oil fields, a large amount of water should be pumped to cool the drill heads and also to wash away the boring holes that require the use of a duplex pump. The ability to move large amounts of water allows drilling kits to work at a much faster rate than those equipped with a one -stage pump.

is also used by duplex pumps drawing diesel fuel and heating oils that do not require heating. The thin viscosity of these oils allows the pumps to transmit them to DorThe bags and also walked through the sieves to clean them with dirt. Stronger oils require heating to draw. Thin make-up of heating oil allows you to flow freely at high speed pump oils.
