Ejectors

TeamTec Ejectors (eductors) are jet pumps driven by water or oil supplied from conventional pumps. TeamTec Ejectors have the combination of high quality material and skilful construction, offering the most effective solution to meet onboard requirements.

Wide Range

Stripping ejectors, which have become standard on most ships being built today are efficient liquid jet pumps for stripping of cargo tanks, ballast water tanks, cargo holds, engine rooms, bilge, etc.

TeamTec also has ejectors for other specific purposes such as mud mixing, degassing, vacuuming, evacuation of air, and from the smallest to the biggest we tailor-make all our ejectors to meet any needs. If we don’t have the ejector you request, we design one!

High Efficiency

The result of using our high efficient ejectors could be smaller piping dimensions, smaller driving pumps and less cost. “In line suction” ensures maximal suction capacity with the use of minimal driving liquid.

High Grade Material

Standard TeamTec stripping ejectors with capacity of more than 100 m³/h are made in Ni-Al-Bz EN 1982, while smaller sized ejectors are made in Gunmetal / RG 9 NS 16520.

All ejector nozzles are made of AISI 316 L or, as an option, monel. Ejectors used for liquid purposes are granted up to 20 years of warranty!

We also produce ejectors in stainless steel and super-duplex.

In-house Casting & Production

We design, cast and test our ejectors in-house, which ensures high quality and flexible delivery time. It also allows special solutions and full utilization of existing / onboard pumps, as we do any flange standard.

Semi-portable (A-ejectors)

The ejector is intended to be lowered into the cargo hold until the inlet bell reaches the bottom of the cargo hold. Driving water is normally provided from the fire pump. All cargo ships without permanent and dependable stripping ejectors mounted in the cargo hold stools ought to have an A-series ejector on board for emergency use.

Indispensable for removing of mud & remains in the ballast tanks.
The ejectors can be delivered with hose or flanged connections.

Installation

When installing TeamTec stripping ejectors or ejectors in general, it is very important that the pipe dimensions connected to the ejectors have min. dimension to corresponding connections on the ejectors.

TeamTec “in line suction” design gives a higher efficiency than “conventional” ejectors with suction 90° from the side. In order to make use of this advantage we recommend the following:

  • Suction pipe connected to ejector is recommended to have straight length prior to the suction flange

  • If a bend is fitted close to suction flange on ejector, suction capacity will be reduced due to turbulence in the sucked liquid

  • Bends on driving water inlet are of less importance as these will create pressure drops which have to be calculated for the planned installation (same applies for discharge side of ejector)

  • It is not recommended to install a bend directly to the discharge flange because of pitting in the bend. Minimum distance between the discharge flange and the first bend should be 3 times the pipe diameter.

Illustrations

Keep in mind

Correct installment

The ejectors can be installed horizontally, vertically or inclined and in order to achieve the maximum performance, the ejectors should be installed as low as practical possible in the hull to keep the suction lift at a minimum. In addition it is of great importance for the performance that a straight pipe length is fitted prior to the suction inlet of the ejector. This straight length of pipe will prevent turbulence in the suction inlet to the ejector thus securing the maximum suction performance.

Prevent pitting

A bend fitted prior to the suction intake on the ejector will reduce the suction capacity equal to 2 mwc increased suction lift. At the discharge outlet of the ejectors we recommend a straight pipe length at minimum 3 x pipe dia. before the first bend/valve is fitted. This length is of no importance to the function of the ejector but it will prevent pitting inside the bend if the bend is fitted direct to the discharge flange on the ejector.

FAQ

Ejectors do not loose suction ability, have large internal clearances and no moving parts. These are some of the reasons that the ejectors are often used instead of ordinary pumps.

Our standard stripping ejectors are made of high grade bronze alloys, having a nozzle in monel metal or in AISI 316. However, we are able to offer ejectors in a wide range of other high quality materials, such as super duplex.

The high grade of material enables us to offer 5-20 years warranty for the product, which normally will operate maintenance free throughout the ship’s lifetime.

Criteria for selection of customized / proper sized ejectors:

  • Installation purpose

  • Liquid type

  • Required suction capacity

  • Estimated suction lift

  • Estimated discharge height

  • Driving pressure/flow

  • Flange type

Please fill in the following questionnaire and return to us for calculation in order to get an ejector special made for your purpose.
