DV type submersible vortex non - blocking pump Overview: DVD-type submersible vortex non-blocking pump is the latest in a line of submersible vortex non-blocking pumps developed by Ebara Corporation. It has the advantages of high efficiency and non-clogging. It is suitable for conveying sewage liquid containing suspended solids and fibrous fabrics (such as plastic products, cloth strips, nylon, wood chips, bones, feces, etc.). The diameter of solid particles is not greater than the discharge diameter, and the length of fiber is not greater than 5 times of the discharge diameter. It can be used to remove water from factories, mines, fish farms, garden drainage, kitchen drainage, livestock farms, feces treatment and other places of sewage treatment. The medium temperature is 0 ~ 40℃, and the maximum submergence depth is 8m. Pump inlet pressure shall not be higher than 0.6mpa. Range of parameters: flow Q 3.6 ~ 282m3/h Head H 2 ~ 39m Model Description: 100DV-B5×11 100 -- suction diameter 100mm, 100 -- discharge outlet diameter 100mm, DV -- submersible eddy current non-blocking pump, B -- impeller size code B, 5 -- frequency 50Hz, 11 -- motor output power 11kW. Structure: the submersible eddy current pump is single - stage single - suction vertical. The impeller is eddy current type, and the pump shares the shaft with the submersible motor. The shaft seal is a mechanical seal. The bearing adopts rolling bearing and is lubricated with thin oil. Direction of rotation: The pump rotates clockwise from the motor end. Main parts material: generally gray cast iron, but also according to the user needs to choose other materials. Range of complete set: pump and vertical submersible motor directly connected with supporting supply, without base. In order to prevent the motor from overheating and burning loss, the motor is equipped with a protective device: the motor with the power of 0.4 ~ 7.5KW is equipped with an automatic circuit breaker. If the internal temperature of the motor is too high, the motor coil loop will be automatically cut off. When the temperature drops, the motor will automatically close and continue to work. The heat dissipation device is installed in the motor with power of 11 ~ 22kW. It is equipped with components to detect the temperature of the motor. Therefore, the circuit can be cut off through the relay in the control disk on the ground. DVA pump is automatic control type. The pump is the same as DV type. Only a set of automatic water level control instrument is added to realize the automatic control of opening and stopping. When ordering, please indicate the material of impeller and sealing ring. If you have special requirements for pumps and motors, you can negotiate with the company about technical requirements.
