100 hp Horizontal Centrifugal Pump, Single Stage

Centrifugal water pump featuring maximum flow 130 m³/h (572 gpm), maximum head 132m (433ft) and 315mm nominal diameter of impeller. Single stage centrifugal water pump has advantages of stable operation, low noise, low failure rate, convenient maintenance, and less land occupation.

Features:

1. The centrifugal pump has the horizontal structure. The diameter of the inlet and outlet are the same. 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. Horizontal centrifugal pump can be operating in series and parallel connection according to the requirements of flow and head.
4. The installation angle of pump outlet can be 0°, 90° and 180° to meet different connection occasions.

Tips: Requirements for the Centrifugal Water Pump Installation Position.

The premise of continuous operation of the centrifugal pump is that the suction pipe must be filled with water before the pump start-up, otherwise the water will not be sucked up. In order to ensure that the suction pipe has no evacuation phenomenon due to pumping termination, it is necessary to solve the problem that the water suction pipe can be filled with water in both water pump stoppage and operation conditions. There are two installation position on site:

1. The pump spindle is located below the water surface of the suction pool. This method is also called self-irrigation method. In other words, regardless of whether the water pump is running or not, the suction pipe is always under the action of the hydrostatic pressure of the water surface and the hydrostatic pressure of the water level of the pool to the center height H of the suction pipe, the suction pipe is always in a status of full of water.
   This method is quite common. The water pump can be started and stopped at any time requiring no measures.
2. The water pump spindle is above the suction water level. When the water pump stops operating, the water in the suction pipe will flow back into the pool by the elevation difference. The suction pipe will be drained. If the water pump is started once again, it is required to fill in the suction pipe. However, such an operation is not practical. At this moment, it is only required to install one bottom valve on the end of the suction pipe(namely play the role of the  check valve), the emptying condition of the suction pipe can be stopped.
   In such installation means, one water pump can be connected on the water outlet pipe of the water pump for water filling. The air in the suction pipe and pump body can be eliminated through the vent valve on the pump body. Generally, if the bottom valve has no fault, the water pump can work normally.
