DESMI Modular H

The DESMI Modular H pump series is the result of further development of the well-known DESMI Modular S pump series. The aim has been to produce a series of non self-priming horizontal pumps, based on the same components as the S series.

The H pump series has been computer designed in accordance with the latest principles, and the result is a modern, compact pump of ideal dimensions for simple and quick dismantling.

By means of an intensive further development both the efficiency and the capacity of the Modular H series have been improved compared to the S series.

The modular principle is based on a simple construction of standard components which secures easy servicing and low spare parts costs. Eventually, the Modular H series will consist in total 33 sizes. The Modular H series meets the demand for economical and reliable pumps. The Modular H pumps are the result of more than 50 years' experience producing pumps, supplied to customers all over the world.

DESMI Modular H special advantages.

• Modular construction
• The pump casing conforms to DIN 24255
• Can be supplied in monobloc combination
• Can be supplied for vertical mounting
• As standard the Modular H series is supplied with gauge points on both suction and delivery principle which will be thoroughly described below.

Developed according to the design of the future

The Modular H series has been developed by DESMI's own development department, applying the latest technology e.g. EDP for the construction of the special Modular H design. The DESMI development department is continuously producing new ideas and is thus enabling DESMI to be in the front rank with new products for the benefit of the many thousand users of DESMI pumps all over the world.

DESMI Modular H modularization

Irrespective of size and capacity the Modular H series is constructed of 5 standard components:

1. pump casing
2. impeller
3. bearing housing
4. suction piece
5. shaft seal cover
