High Volume Water Pump Made in China

Product Description

Brief introduction

This product is a new type vacuum suction pump design based on recycled water as the working fluid, the principle of negative pressure produced by jet. It is provide vacuum for chemical experiments and also can provide circulating cooling water to the reaction set.

The pumps are widely used in evaporation, distillation, crystallization, filtration, decompression, sublimation and so on. It is the ideal equipment in universities pharmaceutical, chemical, food processing and other areas in laboratory.

Features

1. Water-saving effect is remarkable. The water in the water tank of the machine can be recycling, which is overcome the phenomenon of large amount of waste water when direct blow down tap water for vacuum. After testing, in one working day, continuous use may save water more than 8 tons, and the water can be use for a long time at a time. It is particularly suitable for tall building laboratory which is lack of water or insufficient water pressure.

2. Multi-function versatility application. This machine can provide vacuum conditions, besides, it also can provide circulating cooling water to the reaction device. This machine is connected to water, through appropriate supplement water, can continuous cycle operation for long time and keeping the inside temperature does not rise, the vacuum does not drop. Different models have different vacuum taps device, ranging from 2-5, the operator can work alone or in parallel operation.

3. Corrosion-resistant, no pollution.The machine shaft made of stainless steel material: the pump head, impeller, jet device and other key components.Using acid, alkali resistance A.B.C engineering plastics, copper, plastic Wang and other materials, plastic materials for the water tank.According to user needs can be freely chosen, is not from the effects of corrosive substances such as acid, alkali solvents and so on and also does not contaminate the laboratory.

4. Novel appearance, easy to operate. The pump head directly immersed in water, minus the complicated water diversion devices. Bottom with brake caster, easy to move, the upper part with detachable table cover, easy to add water, ice or overhaul.

5. The machine running low noise, stable performance. Also have the advantage of a small size, small footprint, light weight and so on.

FAQ

Malfunction

Failure causes

Maintenance method

Without the vacuum

1. Vacuum nozzle is blocked by foreign body.

2. The filter in the lower part of the pump is blocked by foreign body.

3. Vacuum nozzle coil buckling loosened.

1. Elimination the foreign body in nozzle hole.

2. Elimination the foreign objects on the filter, keep the water clean.

3. Tighten the threaded by hand.

Vacuum meter hand do not move or swing

1. The ventilation key way. behind the vacuum gauge is blocked.

2. Vacuum hands swing, maybe the backwater valve leaking or vacuum nozzle leaking.

1. Remove the vacuum gauge, cleaning up the ventilation keyway.

2. Tighten connection plug of each hose, check backwater valve or valve pad, cleaning backwater valves, fastening vacuum nozzles

Does not start or leakage

1. After power on, motor buzzing does not start is blade stuck.

2. The motor does not turn suddenly is the lines of power or insurance have been cut off.

3. Chassis hemp hand, mostly is the line do not secure socket shell or socket did not install the ground wire.

1. Cut off the power, rotate the fan blade in the motor cover helps to move again and then open it again.

2. Check the line, replace fuse, and dredge the circuit.

3. Exclude socket shell phenomenon, add ground wire socket.

Matters needing attention

Because the pump adopt mechanical seal, please add water before use it. It is forbidden to empty running it in case of mechanical seal parts is damaged.
