Overview

ZBF-type self-priming plastic magnetic drive centrifugal pump referred to (self-priming plastic magnetic pump) is combined with the new nano-materials, structure and self-priming magnetic drive technology, and technical staff after the company repeated research trials and successful high-tech products, self-priming properties, corrosion resistance, no leakage and so on.

Material flow components: PP (reinforced polypropylene), PVF2 (polyvinylidene fluoride)

Connection mode: wire port, hose union, flange

Flow Q: 1.5 ~ 60m3/ h

Head H: 8 ~ 32m

Power N: 0.37 ~ 15kw

Medium temperature (t): 0 ~ 60 ℃

Major Performance parameters

Structural features

ZBF product complies with JB/T7742-1995 Standard for Small Magnetic Transmission Centrifugal Pump and is an optimum product for the integrated design of magnetic pump all over the country.Selfpriming plastic magnetic pump adopts an outer recirculation structure combining foreign advanced technology.It is mainly made of reinforced PP with short time of self-priming and long life,a kind of zero-leakage pump for automation long distance control and fluid transmission of strongly corrosive liquid.

Self-priming plastic magnetic pump with external mixing type axial return structure from the suction pump liquid chamber, liquid storage room, volute, back hole, gas-liquid separation chamber and other components. After the pump is started, the centrifugal force, the suction chamber and the remaining liquid into the liquid in the pipeline air impeller stirred into a mixture of gas and water mixture through the volute into the gas-liquid separation chamber, with the flow rate slowed down, leading to gas water separation, air from the pump fluid discharge port, liquid through backwater hole return pump, after several cycles, the air inlet pipe drained to make a certain degree of vacuum pump, to achieve self-priming role.

Environment

Ambient temperature: -20 ~ 40 ℃;

Humidity: 95%;

Altitude: not more than 1000 m (more than should be made when ordering).

Installation and use

◆ Pump should be installed horizontally should not erect, the body can not withstand the weight of the piping, pumps and piping system should maintain a good seal, no loose fasteners.

◆ Unscrew the top of the water pump bolts, adding liquid water not less than two-thirds of the volume of the pump, tighten the bolts.

◆ Should be checked before using the pump, the motor rotation flexibility, consistent with the direction of rotation of the motor turning mark, no jamming and abnormal sound.

◆ The motor starts, slowly open the discharge valve until the pump into the normal working state, then the discharge valve to the desired degree of opening.

◆ The pump is stopped before the work should be closed discharge valve, then close the suction pipe valve.

Precautions

◆ Due to the cooling and lubrication pump bearings is to rely on the media to be delivered, so the absolute prohibition of non-media operation, and should avoid operating without media blackout in the middle and then start work caused.

◆ If the transmission medium containing solid particles, before the pump inlet to add filter, such as those containing ferromagnetic particles, need to add a magnetic filter (The factory has a production belonging optional).

◆ The medium and its temperature should be conveyed in the pump material within the allowable range. Self-priming plastic magnetic pump use temperature <60 ℃, inlet pressure of not greater than 0.1MPa, the maximum working pressure of 0.6MPa;

◆ For transmission fluid is easy to precipitate crystalline media, after use should be promptly cleaned, drain the pump effusion within the net.

◆ Self-priming plastic magnetic pump after a long-running and found pump abnormality (noise, vibration intensifies), should wear dismantling the bearing ring and the end, if the gap between the bearing and the shaft of the impeller axial movement large, should be replaced and the axial bearing ring.
