Positive Displacement Pump

QBY-K Air Operated Double Diaphragm Pump

QBY-K air operated double diaphragm pumps is transfer medium by the strokes of two diaphrams inside both casing. It is not only can exhaust the flow liquid,but also can convey some uneasy flowed medium, which is popular in many different fields.

DBY Electric double diaphragm pump

DBY series electric driven diaphragm pump is driven by cycloidal pinwheel reducer and drives the double diaphragm to reciprocate through the crankshaft slider mechanism, so that the volume of the working chamber changes alternately so as to continuously inhale and discharge the liquid. At the same time, in recent years, due to the breakthrough progress made in diaphragm materials, the service life of the diaphragm has been greatly extended, so it is more and more widely used in petrochemical, ceramics, metallurgy and other industries to replace some centrifugal pumps and screw pumps.

DJ Chemical Dosing pump

Yangtze diaphragm chemical metering pumps, the electrical motor force the connecting rod to drive the diaphragm to reciprocate,  provide the greatest possible metering accuracy when it comes to pumping supercritical fluids. The outlet displacement of the pump can be adjusted according to the stroke length by adjustment knob and the stroke frequency selection switch. The optimal adjustment range of the stroke length is 20%~100%. The digital tube displays various operating station and alarms.

G Progressive Cavity Mono Screw Pump

The single screw pump is an internal meshing closed screw pump. As the rotor type positive displacement pump(the Archimedes' screw pump), a single screw rotates in a cylindrical cavity, thereby moving the material along the screw's spindle. It has strong adaptability to the medium,which can transport various flowable medium , as well as highly viscous, fibrous, medium containing hard suspended or solid particles.

GF Sanitary Single screw pump

The single screw pump is an internal meshing closed screw pump. As the rotor type positive displacement pump(the Archimedes' screw pump), a single screw rotates in a cylindrical cavity, thereby moving the material along the screw's spindle. It has strong adaptability to the medium,which can transport various flowable medium , as well as highly viscous, fibrous, medium containing hard suspended or solid particles.

KCB gear oil pump

KCB gear oil pump is mainly used to transport lubricating oil goods.  Stainless steel gear pump, can transport non-lubricating oils, beverages, and low-corrosive liquids. Equipped with copper gears, it can transport low internal point liquids, such as gasoline, benzene, etc. The pump gears are all made of hard tooth surfaces, and a safety valve is included to protect the motor from overload.

NYP resin internal gear pump

NYP electric internal gear pump works on a similar principle except the two linking gears sizes are different with one revolving within the other. The rotor is a larger gear and also an inner gear, and it has the teeth projecting inside. A minor external gear is mounted, and this is mainly designed for linking by the rotor so that the teeth of the gear connected at a single end. A bushing and pinion can be connected to the pump case that holds the idler within the location.

3G three-screw pump

3A Lobe Pump

3A rotary lobe pump with gear reducer, also known as positive displacement colloid pump, not only has the same uses and features as other gear pumps, but also has its own unique design, lobe contact is prevented by external timing gears located in the gearbox. Pump shaft support bearings are located in the gearbox, which is especially suitable for conveying high-viscosity colloidal materials and won’t change any chemical and physical properties of the liquid.
