Overview

WQ (QW) non-clogging submerged sewage pumps are new generation of products developed with the advanced technology abroad and on the base of the operational characteristics of pumps at home. Featuring distinguished energy conservation, winding and clogging resistance, as well as autom atic installation and automatic control etc., it is especially suitable for handling sewage containing solid particles and long fibre.

Provided with original impeller structure and latest mechanical seal, this pump can be used to effectively handle medium containing solid substances and long fibre. Compared with the conventional impellers, the impeller on this pump uses single-channel or double-channel, which is similar to an elbow of the same section to display outstanding throughput capacity. Plus the reasonable spiral housing to feature high efficiency. Impellers have been subject to dynamic and static balancing test so that there cannot be any vibration in operation.

This pump is given sophisticated hydraulic perform ance, with all performance indexes in accordance with relevant standard specifications. E ver since the products were put into market, they have been greatly recognized by the mass customers for their distinctive efficiency, reliable performance and consistent quality.

Features

1. Designed with large-flow and anti-clogging hydraulic components to have greatly improved the throughput capacity of sewage, it can handle fibre material with a length up to 5 times of pump diameter and solid particles with a diameter up to 50% of pump diameter.

2.Reasonable design, good matching of mator, high eficiency and remarkable energ y conservation.

3.Double-channel mechanical seal in series, made of durable wear and corrosion resisting hard tungsten carbide to enable pump working safely for continuously over 8,000 hours.

4.Compact structure, smal volume, easy to move and install, no need of pump room, work when submerged into water, great economization ofconstruction cost

5.Oil and water probe is fitted inside oil chamber. Once the mechanical seal at pump side is dam aged and water comes into the oil chamber, the probe will send out signals to carry out protection to the pump.

6. Upon request, it can be fitted with full automatic safety protection control cabinet to carry out monitoring control on the water and electrical leakage, overload and over temperature etc.Thus to ensure reliable and safe operation.

7. Double guide rail auto coupling installation system to bring great easiness to installation and maintenance, so that people are not obliged to get into the sewage pit.

8. Float switch can control the stop and tart of pump automatically according to the change ofrequired water level, with no need of a special person to care about it.

9. Service within the range of head to ensure motor not overloaded.

10. According to service conditions, motor can adopt water jacket type external circulation cooling system to ensure the safe operation ofpump under waterless (dry) conditions.

11.Two types of installation, fixed auto coupling installation and movable tee installation to meet the needs of different service conditions.

Applicability

1. Drainage of seriously polluted wastewater in industrial andcom mercial areas.

2.Drainage system in municipal sewage plant.

3. Sewage drainage station in residential areas.

4.Drainage station in national defense system.

5. Sewage drainage in hospitals and hotels.

6. Municipal and construction projects.

7. U sed as auxiliary equipment in exploration and mining.

8. Methane pool and farm land irrigation in rural areas.

9. Water supply equipment in waterworks.

Service Conditions

1. Temperature of medium not over 60℃ , gravity 1.0~1.3kg/dm²,PH within 5-9.

2. For pumps without internal gravity circulation cooling system , the part ofm otor revealed out of liquid surface should not exceed 1/2.

3.Normally, pump must work within the range of its head so that motor won't be overloaded. If it is to be used in full head,please point out separately when placing an order for our convenience to make the right product for you.

4.In the process of operation, the current of motor shouldn't exceed its rated value.
