Product Description

emai: ***** EXECUTION STANDARD EN***-DIN****5 "End-suction Centrifugal Pump—Designation, nomial duty point and dimensions" / ISO***8 "Technical Specifications for Centrifugal Pumps—Class Ⅲ" PERFORMANCE Caliber: *0~**0mm Capacity: 5~***0m3/h Head: 3~**0m Speed: ***0r/min、***5 r/min Temperature: **5℃ ~**0℃ Maximal pressure: *0bar APPLICATION AC pump is used in heating supply and central air-conditioning system, such as hot water and freezing circulation, firefighting, water supply for industry, water supply for city, irrigatrion, refrigeration (glycol), compression system, water treatment equipment, lighter hydrocarbon treatment. PRODUCT FEATURES AC pump uses grease-lubricated bearing of large size which can run steadily for long time. Bearing options are various, double row angular contact bearing mating with deep groove ball bearing, or using a pair of double rows deep groove ball bearings. The mechanical seal can be in different fixing ways and pressure-bearing capacity. Packing seal and other seal types can also be used. The impeller has axial balancing hole which can reduce axial force effectively and prolong the lifetime of the bearing. The coupling is coupled by flexible pin. The pump can also be mated with lengthened shaft coupling, diaphragm coupling and so on. AC pump is efficient and the efficient zone is wide. The impeller can be cut for many times to meet the requirement of the user which make the energy-saving effect markedly. The pump has low noise and little vibration. It run steadily and has a long lifetime. Its appearance is novel and nice and the structure is compact. MATERIAL The material of flow passage parts: Cast iron HT**0. Nodular cast iron QT****7, QT*****8. Cast steel ZG******0. Stainless steel **4, **6, etc.
