WQ/WQDseries submerged sewage discharfe pump(referred to as
electrical pump hereunder)consists of three components. Water pump,
sealing and electrical motor.
The motor is mounted on top of pump and divided into single phase
and three-phase a synchronizsd types. Double-face mechanic sealing
is mounted is mounted between pump and motor. O shaped oil-proof
rubber sealing ring is used at each stationary port as
staticsealing. This series features themechanic seala for the key
parts are made of hardened alloy and excellent sillico carbide and
characterized bygood anti-corrosion, anti leadage and higuly
durable performances etc.
The pump series is widely used for sewage treatment of city
cionstuction sewage and waste discharge for archiecture projects,
hotel. Mine. Pond. Dyeing and printing, paper making and textile
industries, it is the ideal tool for transportation of sludge,
slurry, living sewage and feces and stale wastes and solid grains
containing fiber. Paper chips. Sandy soil etc.
The pumps can operate properly and continuously under following
1. Working medium carries nop corrosives, sand contents shall be
max. 2% bu volume.
2. Medium temperatuer shall be lower than40? Cand pH shall be 4-10.
The pumps operate within the nominal delivery range.
3. The pumps shall be fully submerged into water with submerged
depth of less than 3m and max. Depth of 5m.
4. The pumps shall be min. 0.5m over the water bottom and shall not
be inserted into sludge.
5. Power frequency shall be 50Hz. Single phase voltage 22oV,
three-phase voltage 380V and voltage fluctuation shall be
0.9-1.1times the nominal
