WQ/ES Series Light Type Mincing Pump
1. Selected Casing and Impeller
The CAD technology is used to repeatedly modify the design, so that the impeller and the cutting module are
optimally matched, and the long fibers are easy to pass through after being chopped, without being entangled
and blocked. The impeller is strictly balanced, so that the pump has low vibration and stable operation.
2. Highly Reliable Submersible Motor
Specially designed and manufactured submersible motor, the protection level is IP68, the stator winding is Fclass insulation, due to the good cooling effect of submersible operation, the actual temperature rise of the
winding is low, so the motor is more durable.
The motor dissipates heat through the casing, and the medium can operate reliably and safely as long as the
medium submerges half of the height of the motor stator. The more submerged, the more conducive to the
cooling of the motor.
The cable is a heavy-duty sewage-resistant rubber-sheathed flexible cable. The cross-section of the cable core
is selected for continuous full-load operation at an ambient temperature of 40°C, which is very reliable. The
cable is fixed twice on the handle to avoid damage during transportation, installation and use.
3. The Motor Has Tight Seals and Strict Inspections.
1) Shaft Seal
Two independent single-end mechanical seals are arranged on the pump side and the motor side respectively
to form two shaft seals. The leakage is only ten percent of the double-end mechanical seal. One below. The
lubricating oil in the oil chamber lubricates and cools the friction pair of the motor side seal. The mechanical
seal on the pump side that is in contact with the medium uses a silicon carbide/silicon carbide "hard-to-hard"
friction pair, which has high hardness and low friction coefficient, which is not easy to wear and fail; the motor
side mechanical seal that is immersed in oil is graphite/carbonized Silicon "soft to hard" friction pair has a low
friction coefficient and is easy to "run-in", and the seal is reliable. The small gap between the impeller and the
pump cover can prevent impurities from entering the shaft seal cavity while maintaining good working
conditions of the mechanical seal. The rubber parts of the mechanical seal are made of nitrile rubber with
excellent oil resistance, and the springs and other structural parts are made of stainless steel.
2) Completely Sealed Cable
The WQ/ES pump motor cable adopts a fully sealed structure with a casting head. The cable sheath, cable
core and casting head are vulcanized into a whole to ensure that water will not pass through the cable sheath
or between the cores. The gap enters the motor cavity. However, the cable end should not be in contact with
water. After all, water entering the cable will seriously reduce the insulation of the cable and affect its safety.
3) Sealing Between Parts
Use O-ring seals as reliable static seals at the joints between the parts.
4) Tightness Inspection
The parts can only be assembled after passing the pressure test. Each pump undergoes strict air pressure test
during and after the assembly process to ensure the airtightness of the motor.
4.Reliable Bearing Configuration
Select the famous brand high quality deep groove ball bearings, which have sufficient load margin to ensure the
reliable operation of the product.
5.Cutting Module
The cutting knife rotates with the rotor at high speed and forms a shearing effect with the cutting disc. Highspeed rotary shearing is performed on the sucked long fibers, and the chopped fibers enter the casing and
follow the rotation of the impeller to be thrown into the pipeline and discharged. The cutting knife is made of
stainless steel and heat treated, and the blade has sufficient hardness to maintain strong shredding
performance for a long time.

The solid part of the curve on the graph indicates the recommended application range of the pump. The user
should carefully check the capacity and head when selecting the type, so that the selected pump can work
within the recommended range.

WQ/ES type pump has three installation methods: automatic coupling installation (Z), hose
movable installation (R) and hard pipe movable installation (Y). The movable installation of the hose
and the movable installation of the hard tube are very simple and need not be detailed.
The following is an introduction to the automatic coupling installation:

WQ/ES Series Light Type Mincing Pump
Automatic coupling installation does not require conventional fasteners to connect pumps and pipes. The coupling device
has only four parts: the outlet pipe seat, the guide bar, the guide bar frame, and the coupling frame. The guide bar only plays a
guide bar and is not subject to force. It is enough to use ordinary water pipes or steel pipes to cut to the required length
according to the depth of the pool, so users can prepare by themselves. When installing, install the outlet pipe seat, guide bar
and guide bar frame, install the coupling frame on the casing, lift the pump, penetrate the semicircular hole on the coupling
frame into the guide bar, and slide the pump down along the guide bar At the end, the coupling frame will be aligned and
fastened with the outlet pipe seat. When the pump needs to be repaired, just lift the pump up and the pump and the outlet pipe
seat will be disconnected. This installation method is very convenient for pump maintenance.
Since the coupling device and the pump are relatively independent, if your pumping station needs to be replaced with a
low-head or high-head pump of the same caliber due to changes in conditions, you can still use the original coupling device.

1. The product name, model, installation form, etc. should be indicated when ordering.
The influence of the medium's severity on the power should be taken into consideration when selecting the model.
Users are warmly welcome to consult the company's technical department for technical questions.
2. The standard length of the motor cable is 10m. If other lengths are required, please specify and indicate on the
order.
3. The complete set of supply parts is supplied according to the installation method selected by the user. Optional
parts and spare parts must be ordered separately by the user.
4. Due to the concise design of the coupling device, the guide bar only needs to use general water pipes or steel
pipes. We have provided the specification and length calculation method of the water pipe or steel pipe used as the
guide bar. The user only needs to purchase the water pipe or steel pipe by himself and cut it to the required length
before use. Therefore, the guide bar is not used as a coupling installation. The complete set of supply parts. When
the user needs the guide bar provided by our company, it must be ordered separately and written in the order.

1. Overview of Control Cabinet Products
The KQK-E control cabinet for this series of submersible sewage pumps is an economical, safe, reliable, and easy-to-maintain
automatic control system. The control cabinet adopts low-voltage electrical appliances and liquid level sensors of well-known
brands at home and abroad, with protection functions such as short circuit, phase loss, and overload. The control cabinet can
adopt common relay control or panel controller control, and it is equipped with float level switch, water level electrode and other
liquid level sensors. In the case of unattended, it can automatically control the start and stop of the water pump according to the
level of the liquid. Except for single-control products, all products with main and standby pump control have the function of
automatically shutting down the faulty pump and automatically turning on the standby pump. The two-pump and three-pump
control cabinet can realize automatic alternate or cyclic operation to realize the equal running time of each pump.
Commonly configured control cabinet components are mainly domestic well-known brands such as Tianzheng, Zhengtai,
Delixi; high-end configuration control cabinet components are mainly internationally renowned brands such as Schneider,
Siemens, and ABB. For a control cabinet with one control and two, if the panel controller solution is adopted, the box size is
400×300×200 (height×width×thickness).
