Spare parts for pumps:
The 4N5x4 electric pump unit is designed for pumping water, oil, liquefied hydrocarbon gases, oil products and other liquids similar to those indicated in their physical and chemical properties.
- Delivery - 62 m 3 /h
- Head - 212 m
- Temperature of the pumped-over medium - no more than 200 & # 8451; C
- Inlet pressure - no more than 0.6 MPa (6 kgf / cm 2 )
- Allowable cavitation reserve - no more than 5 m
- Rotation speed (sync.) - 3000 rpm
- efficiency - at least 63%
The root-mean-square value of the vibration velocity, measured on the pump casing in the area of the bearing support, is not more than 4.5 mm / s in the nominal mode and not more than 7.1 mm / s in other modes.
Scope of delivery
The delivery set of the unit includes:
- assembled pump with counter flanges;
- drive motor;
- coupling with guard;
- common base frame for pump and motor;
- spare parts kit;
- technical operational documentation.
The pump is a centrifugal, horizontal, four-stage pump with a back-to-back arrangement of impellers. The inlet and outlet nozzles of the pump are located horizontally. Connection of branch pipes to pipelines - flange. The rotor is supported by crankcase lubricated rolling bearings. The end seal is gland type.
An elastic sleeve-finger coupling is used between the motor and the pump. An electric motor is used as a pump drive 1VAO-280Y-0.38-2U2, with a power of 90 kW, a synchronous speed of 3000 rpm, a supply voltage of 380 V. The brand of the engine is preliminary and can be replaced by customer's requirement.
Pump and motor are mounted on a single frame.
Material of the main pump parts: casing, cover, impellers - SCH20, shaft - steel 40X.
