Diaphragm pumps are positive displacement pumps that utilize reciprocating motion to drive a flexible diaphragm, thereby conveying fluids. They primarily consist of a drive end, a hydraulic end, and a diaphragm assembly. The drive mechanism drives a piston or plunger in a reciprocating motion; through hydraulic fluid or a direct mechanical connection, this causes the diaphragm to bulge toward the pump chamber, creating a vacuum that draws in fluid. During the reverse stroke, the diaphragm squeezes the fluid out. This “suction-discharge” cycle forms the basis for continuous fluid conveyance. These pumps are widely used across various industries, including oil and chemical processing, environmental water treatment, food and pharmaceuticals, and mining and metallurgy.
By adding a diaphragm chamber to the reciprocating positive displacement pump, a large-sized diaphragm separates the pump's fluid end from the power end. This design achieves high flow rates, high working pressures, and minimal pulsation, enabling leak-free transportation of flammable, explosive, toxic, and hazardous liquids. The product complies with Chinese National Standard GB/T9234-2018, Mechanical Industry Standard JB/T8697-2014, and international API674 standard.
The DGS100 horizontal triplex reciprocating single-acting diaphragm pump features a horizontal triplex reciprocating design. It reliably conveys fluids via a single-acting diaphragm, effectively isolating the power end from the fluid end to ensure zero leakage of the conveyed medium.
The DGS150 high pressure process diaphragm pump is a positive displacement pump that uses hydraulic power to drive the diaphragm in a reciprocating motion for fluid transfer. It operates at significantly higher pressures than conventional diaphragm pumps and is specifically designed for precise metering and reliable delivery in high pressure applications.
A reciprocating positive displacement pump designed for transferring water, water-like chemical liquids, as well as corrosive and non-corrosive fluids with viscosities up to 1,500 cps. Flow rate is adjustable within the range of 0–100%. The product complies with Chinese National Standard GB/T7782-2020 and International API 675 Standard.
