Product catalog summary

Overview of DESMI Modular H Horizontal Centrifugal Pump:
The DESMI Modular H pump series offers several advantages, including modular construction, compliance with DIN 24255 standards, and options for monobloc combination and vertical mounting. Standard features include gauge points on both suction and delivery sides.

Construction and Components:
The Modular H series is constructed from five standard components: pump casing, impeller, bearing housing, suction piece, and shaft seal cover. This modular design ensures easy servicing and low spare parts costs.

Development and Efficiency:
The Modular H series is an evolution of the DESMI Modular S series, offering improved efficiency and capacity. It is a compact, non-self-priming pump designed for simple and quick installation.

Performance Specifications:

Capacity Range: 10-250 m³/h (50-1100 US gpm) at 50 Hz; 10-300 m³/h (50-1320 US gpm) at 60 Hz.
Pressure Range: 5-60 mLC (15-200 ft) at 50 Hz; 5-85 mLC (15-280 ft) at 60 Hz.
Temperature Range: Max 80°C (176°F) with standard mechanical shaft seal; Max 120°C (248°F) with special mechanical shaft seal.

Material Specifications:

Pump casing: Cast iron GG 20
Impeller and wear ring: NiAlu-bronze or Cast iron GG 20
Shaft: Acid-proof stainless steel AISI 329
Bearing housing and shaft seal cover: Cast iron GG 20
Mechanical shaft seal: Carbon/ceramics

Applications:
The Modular H series is suitable for marine and industrial applications, including cooling-water, ballast, fire, wash-deck, general service, ground water, wash-down, circulation, and fuel pumps. It is also applicable for contractors and agricultural use.

Catalog excerpts

The DESMI Modular H pump series is the result of further development of the well-known DESMI Modular S pump series. The Modular H pump is a compact pump of ideal dimensions for simple and quick installation. By means of an intensive 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. The Modular H series is a non-self priming pump. Temperature range: With standard mech. shaft seal max. 80oC ~ 176°F With special mech. shaft seal max. 120oC ~ 248°F Marine pumps: • Cooling-water pump • Ballast pump • Fire pump • Wash-deck pump • General service pump • Etc. • 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 sides Irrespective of size and capacity the Modular H series is constructed of 5 standard components: 5. shaft seal cover Industrial pumps: • Ground water pumps • Fire pumps • Wash-down pumps • Cooling-water pumps • Circulation pumps • Fuel pumps • Filling of tanks and wagons Also suitable for "Contractors" and "Agricultural" use.
