Product Overview
WQ serial submersible pump is a new developed pump based on original product, which is more reliable and environmental friendly. Significant breakthrough has been made on water leakage preventing technology.
WQ pump is mainly used in public works, industrial construction, hospital, diggings to transport waste water, slops, city waste water with solid particle and different long staple, especially play a important role in high concen tration slops governing.
Certificate signal and serial No.: (Shanghai) XK06-003-00039.
Product implementation GB/T24674-2009"sewage submersible pumps" standard.
Product Scope
Applicable municipal engineering, industry, agriculture, hospitals, building, hotels, restaurants and other industries, for a variety of conveyor and waste water solids long fibers, municipal sewage and rainwater, but also the raw water transport, agriculture and irrigation.
Features
Using submersible motor, sealing with new type seal cable inlet wire New type seal cable and cable inlet wire ensure when outer cover, core insulating layer broke or cable and inlet wire do not seal tightly, water will not go into motor wiring chamber and motor chamber.
Reliable construction
Specific probe and screw is well sealed to avoid oil going into motor chamber.
Small submersible pump is unique constructed, fast wiring and reliable, occupying less up chamber space.
Big, medium submersible pump is unique constructed as well to avoid upper bearing broke, due to the lentth increased of axis caused by overheating, easy to install and strip; including a water leak protection equipment to protect motor; special axial constructed design can ensure intensity and righdity of shaft.
Most pumps using complete head response technology, this design ensure as long as peak value of motor power is higher than shaft power, overloading will not happen.
Beautiful layout
Third dimension of pump is strengthening.
Wide function coverage area.
Through the modification and updating, the spectrum evenly, covering broader.
Fully protection
Big, medium submersible pump includes 5 protections (Upper floater, down floater, motor thermo-control, bearing thermo-control, water leak protection).
Ordering Notice
Should be specified in the product accurate product model, product name, installation, performance parameters (flow, head, motor power) and the use of voltage;
Control cabinet should stae its start method (direct start, auto step-down start, thyristor soft-start) fluid level control means (float lever, the number of pressure transmitter level), installation (indoors outdoors type);
The company's normal supply cable length: small pump cable ength 6m the remaining pump is 10m, rail length 3m, if the number of users with special requirements, please specifyl
The company's medium-sized water-cooling jacket pump normally not fit, if the water level below the minimum sample required to be equipped with water-cooling jacket, please indicate in the order.
Export experience:
Over 20 years' export experience.

Ordering instructions
Must provide order information:
The required pump model or user operating point flow, head, NPSH, the nature of the medium and temperature parameters and special parameters of the basic requirement;
The pump main parts material (not to specify the configuration according to the sample delivery);
Inlet pressure (if inlet pressure >=0.6MPa, pump casing should equip with high strength material);
The shaft seal type (three are mechanical seal, injectable soft-fillings seal, special seal part, packing seal and so on, it will delivery packing seal if it does not indicate);
The bearing structure type (select according to medium temperature and so on, it will deliver standard fitting if it does not indicate);
Revolving direction of pump (view from the end of transmission, the revolving direction of pump is anticlockwise. It will deliver standard fitting if it does not indicate);
Motor rotational speed, power, voltage, protection rank, insulation grade, cooling method, whether to guard against explosions and so on;
Base: the sample 315 with the following common base frame sizes, frame sizes above 315 with a split base or no base, please specify when ordering;
For spare parts, please indicate the name and quantity of spare parts required;
Ordering, no special requirements to flanges book list data delivery, if any special requests when ordering;
State seal flushing method: wash the external and external washing. Add the rinse water temperature is suitable for <80 °C in water or medium instead of water occasions. For external washing of the water temperature >=80°C or media containing sand and other particles of the occasion;
Flat flange of the pump, with the sealing surface for sealing wire required the contract specified.
Selecting description:
The order of user isn't limited by the data which listed in the sample performance curve and performance parameter chart, this company may design and provide the products specially according to user's actual requirement flow and head;
If it is close to the listed performance parameter, it will prefer to select the standard impeller pump and the high speed pump generally (the premise is that satisfies the requirement of cavitation performance);
If user's required flow and head parameter aren't in the scope of product's large flow and low head operating condition, the matched motor power may confirm and reduce properly according to the actual operating condition point.
if you have special selecting or have the unclear place to the sample, please inquire the technical support department of Shanghai East Pump (Group) Co., Ltd directly.
Recommended spare parts: shaft, mechanical seal, seal ring, packing, bearings, impeller.
