Better Technology Co., Ltd. has been engaged in the pump industry for more than 16 years and has developed and produced numerous types of sewage pumps. Have to say the variety of products will let customers confused about the choice of sewage pumps. How to select a sewage pump?
Today, the company’s engineering designers have made a summary of this for the customers.
5 Tips to Select a Right Sewage Pump Model:
Customers before the selection, first consider the practical use. Generally speaking, according to the process flow, water supply, and drainage requirements, from five aspects to consider, namely liquid conveying capacity, device head, liquid properties, pipeline layout, and operating conditions.
First, flow is one of the important performance data, it is directly related to the production capacity and transmission capacity of the whole device. When selecting a pump, take large flow as the basis, take into account the normal flow, when there is no large flow, usually take 1.1 times of the normal flow as the large flow.
Second. The head required by the device system is another important performance data of pump selection. Generally, the head size should be selected by amplifying 5%-10% spare capacity.

Three, liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, physical properties with temperature c, density d, viscosity u, solid particle diameter and gas content in the medium, etc., this is related to the system of the head, effective cavitation allowance and appropriate pump type: chemical properties, mainly refers to the chemical corrosion resistance and toxicity of liquid medium, is what kind of shaft seal material selection and the selection of pump type of important basis.
Four. Carefully investigate the pipeline layout of the sewage pump system. The general layout conditions refer to the direction of the water delivery height and the water delivery distance, such as the suction data, such as the low liquid level on the side and the high liquid level on the discharge side, and the pipe specifications, length, material, pipe fitting specifications and quantity, so as to carry out the calculation of the head and the check of cavitation allowance.
Five. There are many operating conditions, such as liquid operation T, saturated steam force P, suction side pressure PS, discharge side pressure PZ, altitude, ambient temperature operation is
interstitial or continuous, pump position is fixed or movable.
If you want to be more professional, there is a simple way, that is to hire a professional drainage designer, spend money to buy a professional. Remember the above points, I hope to give you an effective help in the choice of sewage pump!
