A diaphragm pump (also referred to as a Membrane pump) is really a positive displacement pump that utilizes a mix of the reciprocating action of the rubber, thermoplastic or teflon diaphragm and appropriate valves on each side from the diaphragm (check valve, butterfly valves, flap valves, or other type of shut-off valves) to function a fluid.
When the level of a chamber of either kind of pump is elevated (the diaphragm upgrading), pressure decreases, and fluid is attracted in to the chamber. Once the chamber pressure later increases from decreased volume (the diaphragm moving lower), the fluid formerly attracted was forced out. Finally, the diaphragm upgrading once more draws fluid in to the chamber, finishing the cycle. This course of action is comparable to those of the cylinder within an car engine. Diaphragm Pumps generate a hermetic seal between your drive mechanism and also the compression chamber, allowing the pump to transfer, compress, and evacuate the medium with no lubricant.

Split case pumps and called single-stage double suction centrifugal pump, the main features for medium to large flow, head of the working principle of pump operation, the impeller is installed in the pump shell, and tighten on the pump shaft, pump shaft driven by the motor directly. Central a liquidsuction pump housing connected to the suction pipe. Liquid by the bottom valve and the suction pipe into the pump. Liquid on the pump casing outlet connected to the discharge pipe. When the speed of the pump must be, the pressure head and flow rate related to the impeller diameter

Centrifugal pumps are utilized to transport fluids through the conversion of rotational kinetic energy towards the hydrodynamic energy from the fluid flow. The rotational energy typically originates from an electric train engine or electric motor. The fluid enters the pump impeller along or near the rotating axis and it is faster through the impeller, flowing radially outward right into a diffuser or volute chamber (casing), where it exits.
Common uses include water, sewage, oil and petrochemical pumping a centrifugal fan is generally accustomed to implement a vacuum. Overturn purpose of the centrifugal pump is really a water turbine converting potential energy water pressure into mechanical rotational energy.

Multistage pump is a kind of centrifugal pump, and rely on the rotation of the impeller in the centrifugal force, and material. For gas density to achieve the mechanical vacuum pump was out working range, and thus gradually obtain high vacuum. Multistage pump can be used in petroleum, chemical, machinery, mining, light industry, medicine and food and many other industrial sectors. In many industrial production process, such as vacuum filter, vacuum water diversion, vacuum feed, vacuum evaporation, vacuum concentration, vacuum resurgence and vacuum degassing, multistage pump has been widely used. Multistage pump refers to two or more than two impeller pump.

Submerged sewage pump for vertical type submerged type structure, the pump body is immersed in water at work, submerged depth of 0.5 ~ 5 m, and USES the unique single vane or double vane impeller structure, can effectively by 5 times of pump diameter of the fiber material and diameter of caliber 50% solids. The pump adopts the unique impeller structure and new type of mechanical seal, effectively conveying solid and long fibers. Compared with the traditional impeller, the impeller of the pump impeller with single port or shuangliu form, it is similar to a cross section of bending tube with the same size, has the very good flow.

Sewage pump is kind of a pump that it’s head and motor are connected together, and at the same time, can work under the water. Compared with general horizontal or vertical sewage pump, sewage pump compact structure, cover an area of an area small. Easy installation and maintenance, large sewage pump is generally equipped with automatic coupling device can be installed automatically, installation and maintenance is very convenient. Continuous operation time is long. Sewage pump due to the pump and motor coaxial, shaft short, rotating parts weight is light, so carry the load on the bearing (radial) is relatively small, life is much longer than the average pump. There is no cavitation damage and irrigation water diversion. Especially after a little to the operating personnel has brought great convenience. Vibration noise is small, the motor temperature rise is low, no pollution to the environment.

Self-priming pump working principle is: the pump before you start in the pump shell filled with water or it’s already fill with water inside the pump housing. Start after high-speed rotating impeller flow to the vortex in the impeller, shell, then the entry form the vacuum, the inlet non-return door open, within the air into the pump suction tube and the impeller, to arrive at the outer edge. Self-priming pump is a self-priming centrifugal pump, it has compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and have strong self-priming capacity, etc. Line does not need to install the bottom valve, only to ensure storage in pump body before work are quantitative liquid. Different liquid can use different material self-priming pump.

Magnetic drive pump is the application of the working principle of permanent magnetic coupling in the centrifugal pump of new products. Reasonable design, advanced technology, with fully sealed, without leakage, corrosion resistance, etc. By the pump, magnetic pump magnetic transmission device, motor of three parts. Due to the pump body, pump shaft, the magnetic rotor of sleeve completely closed, thus solved the leakage problem, eliminates the oil refining chemical industry flammable, explosive, toxic and harmful medium by pump seal leakage of safe hidden trouble.
A metering pump moves a precise volume of liquid in a specified time period providing an accurate flow rate. Delivery of fluids in precise adjustable flow rates is sometimes called metering. The term "metering pump" is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are far more suitable than most other types of pumps.
