Overview

1 hp vertical centrifugal pump with 5.2m³/h maximum flow, 20.6m maximum head, and 25mm diameter of inlet and outlet.

Features:

The centrifugal pump has a vertical structure. The diameter of the inlet and outlet are the same. 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.
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 vertical centrifugal pump can operate in series or parallel connection according to the requirements of flow and head.
A vertical pump can be installed vertically or horizontally according to the requirement of the pipeline system.

Definitely a dependable pump for both industrial and daily use.

I've been using this 1 hp vertical centrifugal pump for my workshop's water supply, and it's performed well. The flow rate is consistent, and it handles pressure really well without overheating. Installation was straightforward, and it runs quietly compared to others I've used.

First purchase

This is my first purchase in Inverter.com. This 1 hp vertical centrifugal pump is good. The material is solid and looks durable. Because it has just arrived, it has not been used yet. I hope this vertical centrifugal pump will last a long time.
