DESMI Centrifugal Pumps (Vertical Pumps)
ESL
DESMI centrifugal pumps are used as cooling, ballast, fire, and bilge pumps for fresh as well as seawater. The pumps are available with capacities up to 4000 m³/h / 141258 ft3 and delivery heads up to 220 mWC.
Our product range is based on the modular principle which gives interchangeability of the most commonly used items and consequently a quick and safe supply of spare parts.
DESMI pumps are also installed in many naval vessels where special requirements as to materials, shock resistance etc. apply.
Single pumps or complete packages, DESMI’s staff will always find the correct solution. Our world-wide network of subsidiaries and distributors ensures prompt spare parts supply and first-class after-sales-service.

Monobloc vs. Spacer
Monobloc With BearingThe pump is for major capacities and heavy loads, especially recommended where the advantage of the spacer coupling is of no importance and where a small overall height is required.
The pump is equipped with a separate rear cover with a ball bearing and a separate motor bracket. Dismantling of the rotating pump parts is possible without removing the pump casing from the piping.
SpacerThe pump is for high capacities, heavy loads, and high pump speeds. As a special feature the pump is equipped with a spacer coupling which is a combined distance and flexible coupling. This makes it possible to remove the complete bearing housing with shaft, bearings, shaft seal, and impeller without dismantling or loosening the motor or piping.
For high capacities and the resulting larger and heavier electric motors we recommend this pump version because of the easy dismantling of the rotating pump parts in connection with inspection and repair. This special feature is often a requirement within the marine industry where installations must be easy to service.
Design DetailsPumps With Ø 215 And Ø 265 ImpellerSuction and discharge flange dimensions are identical. The line through inlet and outlet is flush with the centre line of the shaft. The pumps are mounted with one impeller wear ring.
Pumps With Ø 330, Ø 415 and Ø525 ImpellerDimension of the suction flange is one size larger than that of the discharge flange. The line through inlet and outlet is tangential offset in relation to the centre line of the shaft. The pumps have two impeller wear rings.
Modular S
A DESMI speciality is horizontal, self-priming pumps where suction is based on the diffuser principle and
the pump itself is able to evacuate the suction line at suction lifts up to 8.5 m / 278 ft.
DESMI Centrifugal Pumps (Horizontal Pumps)
NSLV and NSLHThe DESMI NSLV pumps are constructed for vertical mount (with suction flange downwards) and the NSLH pump for horizontal mounting.
The pumps are particularly suitable for the pumping of water in connection with cooling systems, cooling of diesel engines, as bilge pumps, ballast pumps, fire pumps, brine pumps, pumps for irrigation, fish farms, water works, district heating, salvage corps, army and navy, etc.
The DESMI NSLV and NSLH pumps meet the special marine and industrial market requirements for:
• High efficiency• Low NPSH values• Easy installation/service• Various materialsand further, an attractive price.

Spare Part Kits include:• Bearings• Mechanical shaft seal• O-rings• Gaskets• Washer & nuts• Overhaul manual
The DESLUBE series is a submerged deep-well pump designed for main engine lube oil supply for large two-stroke engines.
The design is based on our long-time experience of manufacturing deep-well pumps as well as the design features from our in-line centrifugal series.
The discharge socket is bolted to the dome flange and thus carries the pump without further suspension to the tank.
The DESLUBE pump should be used where good reliability and flexibility are required. The DESLUBE pump from DESMI puts the advantage of a centrifugal pump into the main engine lube oil supply pump. If the lube oil pressure is dropping, a DESLUBE pump will increase the flow to reduce the risk of severe damage and eventually break down of the main engine.
Benefits:
• Low NPSH
• Low noise
• Low vibration
• Low maintenance costs
• High reliability
• High flexibility

Modular construction Quality materials
The art of transporting water is finding the right solution, with maximum efficiency, for each situation. The DPV series of vertical, multistage, centrifugal pumps is the result of 55 years of experience and the pumps can be used for numerous applications.
The new DPV pump series is revolutionary in terms of energy-savings and efficiency. Corrosion-free materials, advanced production methods and an optimised hydraulic assembly all contribute towards providing a unique example of craftsmanship.
The modular construction of the product enables you to modify the pump according to your specifications.
DP pump application• ME pre-heating pump• Hot water circulation pump• Refrigeration water circulation
pump• HVAC water circulation pump• Technical water pump• Hydrophore pump • Boiler water transfer pump• Chemical clean pump
Low NPSH• Extended life span as a
result of favourable suction conditions
• NPSH-level 0.6 up to 3.8 (Qopt)
Modular construction• Wide range of options• All specials are standard• Short delivery times
