Agriculture Self Priming Pump

Agriculture self priming pump

Agriculture self priming pump General Description
This series pump is horizontal single suction multistage sectional centrifugal pump, owned 6 national patents, and with high efficiency, wide performance, steady and safety operation, low noise, long operation, easy installation.
It can deliver the medium with solid particles (the diameter of the solid particles should less than quarter of the impeller channel), besides, it can be changed the pump materials(or flow channel materials), seal type, add cooling system then can deliver the hot water, oils, corrosive liquid, and abrasive medium.
ZD,ZDG,ZDF,ZDY,ZMD series horizontal multistage pump using temperature range is -60℃~400℃,Material: HT200,QT600,JM3,28#alloy,304,304L,316L,317L,904IL,CD4,Hastelloy C,Hastelloy B for clients choice.
We have passed ISO9001:2000 quality system certification, strictly control the pump design, production and service, totally make sure the pump quality.

Agriculture self priming pump Construction description
1,ZD,ZDG,ZDF,ZDY,ZMD horizontal multistage centrifugal pump adopt the symmetrical setting impeller, it can eliminate the axial force, the remain axial force can born by a pair of back to back angular contact ball bearing. As there is no balance device. that is no friction loss and return loss in the balance disc., so the pump efficiency is greatly higher 5~14% than common multistage pump. So totally solved the problems that caused by the loss efficiency of the balance device, so greatly longer the operation hours .
2, Adopt high-end mechanical seal; Traditional mining multistage pumps all adopt packing seal, the advantage of the packing seal is can anti-abrasive, but there is leakage in the operation.The mechanical seal with no leakage, but when there is solid particle in the medium, its operation hours is short. Now the mechanical seal for our new mining multistage pumps adopt high-end sealing, it combines the advantages of the packing seal and mechanical seal. It can make sure no leakage in long term operation. The mechanical seal is a new patent product
3,The bearing seat can not allow the water in; this technology is our new and patent technology, it can make sure there is no liquid into the nearing seat when pump is working and rest. Greatly length the bearing operation life and reduce its maintenance cost for the users.
