Submersible Sewage Pump

Product details

General Introduction:

QW series submersible sewage pump is developed for sewage water delivery based on the advanced technique from abroad and domestic, adopted the best hydraulic model. It does not only have the advantages of high efficiency, circumvolution proof, lockage free, durable, longer service time but also has the advantages of automatically coupling, automatically control, convenience for installation and move. Especially they are suitable for pumping liquid with solid, sewage, long fibre. QW sewage submersible sewage pump is widely used in municipal engineering, industry, hospital, hotel, building, restaurant for pumping sludge and sewage water.

Operation Condition:

1. Power source: 380V/50Hz, 460V/60Hz, 3 Phase

2. Temperature of the medium under 40℃

3. PH value: 4~10

4. Volume ratio of solid in medium below 4%.

5. Density of medium should be lower than 1.2×10 3 kg/m³.

6. The standard QW pump is not allowed for a flammable and explosive environment, and it is not suitable for flammable or corrosive medium.

If the application is out of the above operation condition, we can supply it by special design following the order.

Type of Meaning:

Structure Characteristics:

QW series submersible sewage pump is vertical bottom suction type pump, it contains a motor, pump and seal system, the pump was driven by the motor through the community shaft. The pump is compact and with status indicators and protection device for pump safe and reliable operating.

1. Our company can supply more pumps which the main parameters out of above table following the order.
   

2. Our company can supply different material pumps following the order.

 Installation and application

The installation modes of QW series pump are fixed installation and removable

installation. The fixed installation includes Auto-coupling installation, fixed wet installation and fixed dry installation. Removable installation also can be called free

installation; the discharge can be connected with flexible pipe and rigid pipe

Fixed installation

1、 Auto-coupling installation

The auto coupling installation can put the sewage pump along guide rail into

sewage fast and simply. The pump and the pedestal can be coupled automatically;

installation,service and lifting are very convenient.

In this installation mode, pump and coupling is corrected before installation. The coupling base is fixed in advance at the bottom of the sump. The fixed bolts

are mounted when the sump is constructed). The pump can be moved freely along guide rail.

2、Water level control switch, terminal box and full automatic control panel is available in this mode following the order. The pump model, installation mode, sump depth, control system of pumps should be provided when consult us for pump model selection.

3、 Fixed wet installation

Vertical installation, the pump is supported by pedestal which is fixed on the bottom of sump. The discharge connected with delivery pipe through Elbow.

4、 Fixed dry installation

The set is installed aside of pump pit which on the pedestal with inlet pipe. Being adopting cooling,it can make the pump operate in full

load,the continuous flowing impact can not 

break the pump,and it is suitable for various

situations for municipal engineering, crossway sewage drainage

Note: The installation mode should be confirmed by customer

 INSTRUCTION TO ORDER
