1. The importance of the basic data of the type selection of self priming pump

The most critical step before buying self priming pump is to understand clearly the basic data of self priming pump selection, and understand the basic data of related self priming pumps before selecting a self priming pump product that meets the requirements of operation.

Two. The basic data of the type selection of self-priming pump:

1, the basic data of the type selection of self - priming pump should first know what medium is the liquid of the conveyer. The main characteristics of the name, the main liquid (such as liquid is not corrosive, recovery, flammable, toxic, etc.), high specific temperature of liquid is not containing particle diameter, particle specific content is what medium number and particle density, the viscosity of the medium.

2. Then determine the performance parameters of the self-priming pump. We first need to understand the needs of the user flow, then need to know the length and height of self suction pump inlet pipe in which the specific areas to facilitate access to the atmospheric pressure calculation of self suction pump suction can not meet the conditions, self suction pump outlet piping layout; specific vertical height height, horizontal distance, how many meters in diameter the number and the number of valves, elbows, self-priming pump pump out what is useful, the end is not need to be stressed so as to select the appropriate product manufacturers self-priming pump lift for you, understand the operation mode of the device (intermittent or continuous operation).

3. Other conditions that should be understood when the pump is chosen. Self suction pump selection should take into account the use of environmental conditions limit, budget cost, installation position and security self suction pump (such as conveying inflammable and explosive liquids or the environment also need explosion-proof motor and environmental pollution) is not in need of self-priming pump without leakage function requirements such as vertical self-priming pump without leakage.
