Structural Characteristics

Pump is vertical structure,motor cover and pump cover are connected to be designed.Beautiful appearance,little occupied area.It can be used outdoor if a protective cover is installed.

Inlet and outlet diameter of pump are the same and they are on the same center line,which can be installed on the pipeline directly just like valves,and the installation is very convenient.

Excellent foot design makes the installation and steadiness of pump convenient.

Pump shaft is lengthened shaft,and this solves the vibration problem caused by coupling drive that is applied by common centrifugal pump shaft and motor shaft.Chromeplate treatment shall be proceeded on surface of pump shaft,which greatly prolongs the service life of pump.

Impeller is directly installed on the motor lengthened shaft.There i no noise when pump is operating,motor shaft applies low noise bearing,which greatly improved the operating environment.What’s more,non-malfunction working time of pump has prolonged 3 times than the common pump.

Mechanical seal is used on the shaft seal,which solves the severe leakage problem caused by packing seal of common centrifugal pump.Static ring and rotating ring of sealing are made of silicon carbide,which prolongs service life of seal.

There is a exhaust hole on the pump cover.Outlet hole and pressure hole are on the flanges downside and two sides of pump casing in order to make pump operate,maintain normally.

Unique structure,so there is no need to dismantle pipe system.Just dismantle pump cover nut,then begin to maintain.It is very convenient.

Series connection,parallel connection and enlarging of pipe diameter can be applied according to requirements,namely,capacity and head.

Max working pressure of pump system≤1.6MPa,namely “pump suction pressure+pump head ≤1.6MPa”.When ordering,system working pressure shall be marked.If pump system working pressure is more than 1.6MPa,it must be specified when ordering so that cast steel material can be applied when manufacturing.

Environmental temperature<40℃,relative humidity<95%.

Volume content of solid particles in the transported medium shall no exceed 0.1% of unit volume,granularity<0.2mm.

Remarks:If medium contains tiny particles,please specify when ordering,so that the wear-resistant mechanical seal can be applied.

Q:Piston filling and peristaltic pump filling which precision is high?
These two pumps are used as a metering pump to use, so the accuracy is to be on a par with the peristaltic pump has more advantages than the piston pump is the largest energy fluid conveying there are particles, and the piston pump is smaller than the peristaltic pump pulse, so we need to choose according to the material characteristics you need to transport.
Q:Troubleshooting of diaphragm pump
The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture
Q:The water tank of the fish tank does not air out and only has the water outlet
The water pump is cut off, the intake pipe is drawn out, and the water in the air pipe is blown out, then the water pump is put on the surface of the water, and the air inlet pipe is inserted on the surface of the water pipe, and then the water pump is put back into the water, and the water pump is electrified. Try again several times at a time. It should be effective.
Q:Must the water pump in the tank be all soaked in water?
Usually you have to soak it all in the water. If you don't want to put it in the water, you can buy an amphibious pump. At most, you can expose it
Q:Working principle and diagram of axial piston pump with pressure compensation variable
The size of the outlet flow pressure compensated variable displacement pump with outlet pressure of approximately in a certain range according to the constant power curve. When the pressure oil from the main part of the channel (a), (b), (c) into the inferior vena cava (d) variable shell, oil by the channel (E) respectively into the channel (f) and (H), when the spring force is greater than the oil (f) into the lower end of the piston ring servo hydraulic thrust area when the oil liquid (H) to the chamber (g), push the variable downward movement of the piston, the pump flow increases. As for the hydraulic servo piston end thrust force ring shaped area is greater than the spring when the servo piston moves upward, blocking channels (H), the (g) (I) through the cavity of the oil cavity pressure relief, at this time, the piston moves up, the variable head angle decreases, the pump flow rate decreases.
Q:Is the vacuum pump air compressor?
No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.
Q:What is the function of the heating pump system for the water pump design?
Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.
Q:What should be used to pay attention to the use of mechanical pumps?
When opening the pump, first close the outlet valve, lift the pressure, then open the outlet valve again, pay attention to the flow of the motor.
Q:What does "anti pump" mean in pump operation?
The pump again is the pump, the theory is the plugging problem can be solved, but if you are against the pump after pump has been plugging serious, and pump has been unable to solve the plugging problem, finally the worst solution is a split pipe, if the situation under enormous pressure will only exacerbate the plugging
Q:The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
1. submersible pumpsA very wide range of water treatment tools. Unlike ordinary water pumps, it works underwater, while the pump works mostly on the ground.The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.Basic parameters of submersible pumpIncluding flow, lift, pump speed, matching power, rated current, efficiency, diameter and so onSubmersible pump main application and scope of applicationIncluding construction, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on
