Areas of Use
- In Fi-Fi (Fire Fighter) system trailers
- In vessels, gland water and sea water pumping
- In big fire extinguishing systems
- In industrial and social plants
Pumped Liquids
It is used in pumping clean and sea water that do not contain solid particles and fibre.
Design
- They are horizontal type, single-stage, single-inlet, suction nozzle on the horizontal axis, discharge nozzle on top, shut-off ımpeller, volute casing centrifugal pumps.
- Since its volute is symmetrical, it can be installed as to operate in both directions. Due to this specification, it can also be connected to left-turn engines.
- ENM pump ımpellers are of double slope type. The ımpellers are dynamically balanced on the electronic balancing machine. Axial thrust force is balanced with back wear ring and balance holes.
- The pumps have a rigid shaft that can operate at different loads.
- Inside the suction casing, there is a plain bearing lubricated with water.
- It has a compact structure due to the short distance between the flexure resistant shaft and the bearing and the volute. Due to this specification, it is available for the applications with limited volumes (such as Marine fire brigade).
- In normal applications, two roller bearings are used. The cantilever bearing used is optional.
Bearing Housing
In ENM series pumps, two types of bearings, as sliding and ball bearings, are used. When the roller bearing is installed on the engine side, the sliding bearing stays on one side and the pump on the other side.
Sealing
As a standard, shaft sealing is ensured by a gland gasket that is cooled and lubricated with pumped water. There is also a mechanical seal option according to the requirements of our customers.
