The SILI CQX submersible pump is also called CQW or QW submersible pump sometimes. It is a kinf of submersible centrifugal sewage pump, with non-clogging impeller, and portable design. This centrifugal marine pump is mainly used for sewage bilge, fire fighting, deck-wash and emergency flood water for marine and off shore purpose.
CQX submersible pump is suitable for sewage, bilge and oily water, max liquid temp 60 C degree, maximum diameter of the solid grain 50% of that of the pump outlet flange Max liquid temp 60 C degree, Max S.G. 1200kg/m3. The maximum diameter of the solid grain going through the CQX submersible pump has not to be larger than 50% of that of the pump outlet flange. Refer to more details from right link onsides the pump catalogue, specification and manual. CQX pump spare parts can be also available in our sides.
CQX submersible pump Design Features:
a. Class F Insulation level, max working temp 155 C degree. The effective seal makes its IP 68 high protective level. An over heating device for the motor is optional.
b. With the optimized design, the big channel impeller (no-clogging type) will not be blocked up when to transport sewage/bilge with big impurity or long fiber.
c. A oil chamber is located between the motor and the pump. Oil can lubricate and cool the mechanical seal and prevent water from penetrating into the motor. A water-leakage probe(above 5kw) is mounted inside the oil chamber to check water leakage and it will give a warning signal, when the mechanical seal on the pump side leaks.
d. Double separate mechanical seal work individually to separate the motor from the pump seal, to provide the motor with a dual protection.
e. Quality bearing with a reasonable configuration, can extend the duration of the pump. At the top and the bottom of the motor, there is both a rolling bearing. While in the bottom of the motor, there is another thrust bearing. (double bearings at the bottom of the motor side).
f. A special cooling water jacket is optional if request.
g. Standard material for bronze for the pump casing, impeller and cover, stainless steel for pump shaft. An optional stainless steel material for pump casing, cover and impeller.
h. Portable design, with a standard 10m water-proof cable. The fire hose and quick connection port can be provided as request.
