The selection of ZW self-priming non-clogging sewage pump should determine the choice of model, material and motor

 

 

The use conditions of ZW self-priming non-clogging sewage pump are flow rate: 5-800m3/h; head: 12-60m; motor power: 2.2-55KW; speed: 1450-2900r/min; caliber: φ25-φ300; medium temperature: ≤100 ℃; ZW self-priming sewage pump height: 4.5-6.0m. It has the characteristics of simple structure, good self-priming performance (self-priming height up to 5m), strong sewage discharge capacity, high efficiency and energy saving, and convenient maintenance (it can completely replace WQ and QW submersible sewage pumps).

 

 

 

  ZW self-priming non-clogging sewage pump is suitable for urban environmental protection, construction, fire protection, chemical industry, pharmaceutical, dye printing and dyeing, brewing, electric power, electroplating, papermaking, petroleum, mining, equipment cooling, oil tanker unloading, etc. It is suitable for clean water, sea water, chemical medium liquid with acidity and alkalinity, and slurry with general paste (medium viscosity ≤ 100 centipo, solid content up to 30%). Equipped with a rocker sprinkler, the water can be washed into the air and sprayed into tiny raindrops. It is a good machine for agriculture, nursery, orchard, and tea garden. It can be used with any filter press of any model and specification, and is an ideal matching pump for feeding slurry to the filter for press filtration.

 

   How to select the ZW self-priming non-clogging sewage pump:

 

Before selecting a model, we must know or have a ZW self-priming non-clogging sewage pump specification model parameter table in order to select the model. We compare the parameter table and our own working conditions to select the model, and also know what the model means, below for example.

 

  50ZW15-30-PB self-priming non-clogging sewage pump model meaning

 

  50 is the inlet diameter (mm);

 

  ZW is a self-priming sewage pump;

 

  15 is the rated flow (m³/h);

 

  30 is the rated head (m);

 

  P stainless steel material (no mark indicates cast iron pump);

 

   B explosion-proof motor (no mark indicates ordinary motor)

 

  Step 1: Selection of ZW self-priming non-clogging sewage pump model

 

  1. First select the caliber of the self-priming sewage pump according to the size of the pipeline. For example, if the pipeline is an 80mm pipeline, we choose the four models: 80ZW40-16, 80ZW65-25, 80ZW80-35, 80ZW50-60;

 

  1. Determine the final model according to the flow and head. For example, if the flow requirement is 80m³/h and the head is 35m, then the final model is 80ZW80-35. It should be noted that the flow and head are not necessarily the same For our actual flow head parameter pair, we only need to choose the similar one, but the head must be greater than or equal to the actual head.

 

  Step 2: ZW self-priming non-clogging sewage pump material and motor selection

 

  1. The material selection of the ZW self-priming non-clogging sewage pump is very simple. The ZW self-priming sewage pump has two materials, one is cast iron and the other is stainless steel (stainless steel is 304, 316, 316L stainless steel). Therefore, if the conveying medium is corrosive, choose ZW stainless steel self-priming sewage pump, on the contrary, just choose ordinary cast iron self-priming sewage pump.

 

  2. The selection of ZW self-priming non-clogging sewage pump motor is even simpler. The motor is divided into: ordinary motor, explosion-proof motor, frequency conversion motor, etc., and you can choose according to the actual situation.

 

  Comprehensive of the above: ZW self-priming non-clogging sewage pump specifications and models, caliber φ25-φ300mm, flow 5-800m3/h, head 12-60m; self-priming height 5m and other specifications and model parameters. It can be seen from the above that the selection of the ZW self-priming non-clogging sewage pump is very simple. The corresponding model is selected according to the size of the pipe, the flow rate and the head, and then the pump body material and motor are selected according to the medium. I believe you will already choose the model. If you still do not, please call our customer service to help you choose the model.
