wide application self priming pump for solid particles

general information

self-priming pump is an energy saving pump and use the mechanical seal of a ceramic ring so as to resist any sandy liquid to go into the sealing face, preventing it from getting scratched. This pump holds the advantages of a compact structure, easy operation, stable movement, easy maintenance, high efficiency, long duration and strong self-suction capacity and, as no foot valve is needed to be mounted on the pipeline and only a certain amount of leading liquid is required to be filled into the pump before work, improves the work condition while simplifying the pipeline system. This pump can be equipped with either Y series common motor or YB series explosion-proof one upon the different surroundings of use.

Application of self priming pump

 1. Widely used in environmental protection, aquaculture light industry, paper making, textile industry, food, chemical engineering, electric power, fiber, slurry, suspension and so on

2. This pump, when mounted with a shaking arm shower, can have the water burst into air and then scattered in a thin drop for spraying, useful to a farm, nursery, orchard and tee plantation.

3. Suitable for pure water and liquid include many solid particles or continuous fiber and unit weight of the medium should not more than 1240kg/m.

3. Medium PH if cast iron: 6-9 Stainless steel: 2-13

4. This pump can work together with a pressure filter of any model and specification and is the most ideal matching pump to send pulpy materials to the said filter for pressure filtering

 Pump Specification 

The installation 

1. With the shafts of both pump and motor linked in action, pay attention to the concentricity between the pump shaft and the motor's output; and carefully mount arcalibrate the pump as which will leave a bigger affect onto the running stability and duration of it

2. Fasten the nut on the pump's clutch, or the impeller maybe made easily movable to cause a mechanical failure.

3. Have the pump inlet higher than the central line of the pump shaft so as to have a certain volume of liquid kept inside of the pump to get a better self-suction capacity and prevent the mechanical seal from drying friction

4. Cautions for the installation of the suck-in pipeline: 

A. The installation height of the suck-in port shall not be over 3 -5m and, if the condition is allowed. lower than the lowest water storing surface as can as possible and make the length of the suck-in pipe as short as possible and the elbow less mounted so as to shorten the self-suction time and enhance the self-suction function 

B. The valve, flange etc, inside of the suck-in pipeline shall be prevented from air or liquid leaking that mean no air-leaking is allowed inside of it.

C. To prevent any solid etc. impurities from sucking in the pump. a filter should be set on the suck-in pipeline. with the effective filtering area 2-3 times the section the pipeline and the filter checked in a periodic time.

D. Get suck-in and vomiting pipelines a stand of their own and do not let the pump bearing any pipeline.
