75 hp Vertical Centrifugal Pump

75 hp vertical centrifugal pump with 224m³/h maximum flow, 76m maximum head and 150mm diameter of inlet and outlet.

Features:

1. The centrifugal pump has the vertical structure. The diameter of the inlet and outlet are the same. And the inlet and outlet are on the same center line, so that the vertical centrifugal pump can be installed in the pipeline like a valve. If a protective cover is added, it can be used in the open air.
2. It is easy to install and maintain. No need to dismantle pipeline system, just lifting off the conjunction flat nut of vertical pump. Then all the rotor parts can be taken out.
3. Vertical centrifugal pump can be operating in series or parallel connection according to the requirements of flow and head.
4. Vertical pump can be installed in vertically type or horizontally type according to the requirement of pipeline system.

Tips: Hazard of the centrifugal pump reversal rotating
The reversal rotating of the water pump can be also divided into the active reversal rotating and passive reversal rotating. The caused hazard differs as well.

Active reversal rotating refers that the motor drives the reversal rotating of the pump, which is mainly caused by the wrong connection of the motor wire. The main hazards include:

1. The mechanical seal with rotating requirement will probably be damaged.
2. The shaft sleeve lock nut, and the impeller lock nut(impeller cap) with the rotating requirement might become loose. If the pin is used for the connection, the influence is not big.

Passive reversal rotating refers to the pump drags the motor to have reversal rotating. The liquid in the pump outlet line flows back into the inlet, causing the pump to have reversal rotating, which drives the motor to have reversal rotating (need to consider whether the motor has power loss at this moment). The main hazards are:

1. The mechanical seal with rotating requirement will probably be damaged.
2. The shaft sleeve lock nut, and the impeller lock nut(impeller cap) with the rotating requirement might become loose. If the pin is used for the connection, the influence is not big.
3. The pump of the balancing disk or balancing drum will probably damage the balancing disk or balancing drum.
4. Cause water hammer and damage the pump structure.
5. The multistage centrifugal pump(guide blade type) will easily cause resonance rotating speed and damage the pump equipment.
