API OH4 Overhung Type Vertical Centrifugal Pumps

The TEFFIKO TLHP series of API OH4 Overhung Type Vertical Centrifugal Pumps features excellent design and manufacturing processes. The shaft is connected by a flange and positioned with a spigot, ensuring high concentricity, low vibration, reliable operation, and convenient maintenance.

The hydraulic flow - through components adopt a high - efficiency and energy - saving hydraulic model. The pump efficiency is 5 - 8% higher than that of ordinary pumps, which can save operating costs for enterprises. The pump body is made by precision casting, with accurate internal structure and an aesthetically pleasing appearance.

This pump is a newly developed generation of single - stage and single - suction chemical pumps. With excellent performance, beautiful appearance, and easy maintenance, it is an ideal choice for pump equipment in the chemical industry.
