Description:
By three element design theory, model optimization design and analyze the pump's dynamic characteristics. To maximize the efficiency of pump, widens the efficient area of the pump, to reduce the noise of the pump.
The impeller is made of stainless steel stamping laser welding technology,has utility model patents issued by the State Intellectual Property Office, patent number is ZL201320534632.7.
The main parts of the casting using resin sand molding,surface smooth. Numerical control machining process for parts,application of three-dimensional detection technology to ensure the conformity of the form and position tolerance,using the theory of module and virtual technology to improve the reliability of the products ,and product is verified by the test system at final.
The efficiency index accord with GB18613-2012 Small and medium-sized three-phase asynchronous motor limited value of energy efficiency and energy efficiency grade 's 2 levels of energy efficiency standards by using the YE2 three-phase asynchronous motor,
At present, high energy consumption situation has become an urgent realistic problem. The actual operation efficiency of pump products and the system efficiency is generally low , waste of electricity each year about 10 billion kilowatt hours. If the pump efficiency increased by 1%, can save 2.2 billion kilowatts Hours of electricity, energy saving effect is very obvious. This series of products has a broad efficient area and high efficiency ,is the company independent research and development made the second generation of the single stage single suction pump. Compared with GB/T13007centrifugal pump efficiencyoverall efficiency increased by 3 to 8% .Of this series of products, aims to set up the pump industry famous brand, is the best choice to replace imported products.

Selecting description:
The order of user isn't limited by the data which listed in the sample performance curve and performance parameter chart, this company may design and provide the products specially according to user's actual requirement flow and head;
If it is close to the listed performance parameter, it will prefer to select the standard impeller pump and the high speed pump generally (the premise is that satisfies the requirement of cavitation performance);
If user's required flow and head parameter aren't in the scope of product's large flow and low head operating condition, the matched motor power may confirm and reduce properly according to the actual operating condition point.
if you have special selecting or have the unclear place to the sample, please inquire the technical support department of Shanghai East Pump (Group) Co., Ltd directly.
Recommended spare parts: shaft, mechanical seal, seal ring, packing, bearings, impeller.
After service
East Pump persist in "consumers' satisfaction" as our objective. "To offer consumers with high-class services" as our promises. They are embodied in our all processes of sales.
Before-sales service: Our engineers offer consumers design and consultation services. They will commend the optimum products, therefore, losses because of unsuitable select of pump can be averted.
