WATER EJECTORS

 

Water ejectors are vacuum pumps, driven by a high pressure water (or similar medium) or steam. They use kinetic energy of the driving medium to suck in gases, vapors or other liquids and then discharge the resultant mixture against a counter pressure.

Turbine Works manufactures water ejectors for industrial and marine purposes.

Ejectors are simple in design and reliable in operation since they don't have movable parts like stadanrd pumps. Major parts of an ejector are a inlet casing, nozzle, mixing chamber and diffuser. Since there are no moving parts, no lubrication is necessary and maintenance is minimal. Ejectors are self-priming and easily activated by simply turning on the flow of the driving water.

WATER EJECTOR ESH 65-65-80

Water ejectors depending on application can be manufactured out of various materials ranging from bronze, steel, stainless steel with nozzels usualy being made out of hi grade stainless steel or monel.

Ejector defining paramters are:

Qs - Suction capacity
Hd - Delivery head
Hs - Suction lift
Qd - Driving medium consumption
Pd - Driving medium pressure at ejector inlet

Follow this link to se these on a installation schematic for better understanding!

MARINE WATER EJECTORS

Due to their excellent suction capability and reliebility, water ejectors are frequently used for marine applications shuch as:

Ballast stripping ejector
Bilge stripping ejector
Chain locker ejector
Sewage (black) water vacuum suction
Misc. other applications

Their above applications and size which can vary from 50 cm to more than few meters, make them significant part of ship's engine room equipment.


Below is the table with TTK standard water ejectors and their most typical driving parameters. Please contact us for your exact requirements.
