Overview

7.5 hp horizontal centrifugal pump with 7.8m³/h maximum flow, 72m maximum head, and 40mm diameter of inlet and outlet.

Features:

The centrifugal pump has a 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. There is no need to dismantle the pipeline system, just lift off the conjunction flat nut of the vertical pump. Then, all the rotor parts can be taken out.
A horizontal centrifugal pump can operate in series and parallel connection according to the requirements of flow and head.
The installation angle of the pump outlet can be 0°, 90°, or 180° to meet different connection occasions.

Tips: Operation steps of centrifugal pump startup

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.

Ideal 7.5 hp horizontal centrifugal pump

I purchased the 7.5 hp horizontal centrifugal pump for my commercial building's HVAC system. It is a reliable and efficient source of water circulation with a high flow rate and can handle a wide range of fluids with ease. Not bad.

I will buy a 7.5hp horizontal centrifugal pump again

Used this to replace another yard irrigation pump pulling water from the lake to irrigate the yard. Working great and easy to install for our sprinkler system. I will buy a 7.5hp horizontal centrifugal pump again.
