Centrifugal water pump has maximum has optional input voltage AC 230V/ 240V/ 380V/ 440V to 480V and optional input frequency 50Hz/ 60Hz. Horizontal centrifugal pump has 0°, 90° and 180° installation angle of outlet.

Features:

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.
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.
Horizontal centrifugal pump can be operating in series and parallel connection according to the requirements of flow and head.
The installation angle of pump outlet can be 0°, 90° and 180° to meet different connection occasions.

Tips: Operation Steps of Centrifugal Pump Start Up.

After completing preparations, the centrifugal pump can be started. After starting, when the pump speed is stable, check the pressure and current, and pay attention to the vibration and noise. When the ammeter pointer swings to the specified position, the cock of the vacuum gauge and the pressure gauge can be opened, and the outlet valve must be slowly opened, and the water pump starts to have the normal operation. At the same time, the valve of the sealing water pipe should be opened.
The idle running time after the start of the centrifugal pump should not be too long, usually limited to 2 to 4 minutes. If the time is too long, the temperature of the water will rise, which may cause cavitation or other adverse consequences.

Some questions about pump

What is the head lift on this pump I'm going 30' in the air through an 2" pipe for firefighting It'll be carrying water. Also, will it trip out if it can't expel all the water at once. It's on a spray system.

1. This pump has different heads for different flow rates, for example, the rated flow rate is 7.8 m³/h (18gpm), and the maximum head is 65m.
2. Yes, for the sprinkler system, if it cannot expel all the water at once, it will trip out. Usually in the sprinkler application system, there will be a control cabinet to automatically control the pressure of the sprinkler system.
When the upper pressure limit is reached, the pump automatically stops and when the pressure is maintained at a certain level and the pressure is reduced to a certain level, the pump automatically starts.

Powerful Pump

When I received the product, it felt heavy. The quality should be good. I wonder if the horizontal centrifugal pump can be used for freshwater treatment? I have some fish in the pond at home, mainly for viewing.
