Penberthy Jet Pumps provide a practical alternative to more complicated and expensive methods, jet pumps offer simple, more cost-effective ways to pump, mix or heat a wide range of liquids and gases used in the process industry. Jet pumps can operate with a wide variety of motive liquids and gases. If you recognize any of the above terms, you can probably use a jet pump..  Our jet pumps / eductors feature the newest ideas in eductor design and manufacture, ideas that provide real user benefits.  The Penberthy brand has been recognized for global leadership in the design and manufacture of innovative products for the process industries since 1886.  Jet pumps are great for pumping and/or mixing liquids as well as inline steam heaters.  There are no moving parts so they are very easy to install and maintain.  The product is supported by a knowledgeable staff, large inventory and ISO9001 Manufacturing.

Product Overview

There are eight models of Penberthy jet pumps available for pumping gases:
Models LM and ELL are used for exhausting, evacuating and priming operations where a liquid operating medium is available. They are available with suction and discharge fittings ranging from ½” to 12”, depending on the type of construction.

Model FL ‘fume movers’ also use a liquid operating medium and are available with suction and discharge fittings ranging from ½” to 4”.

GL and GH models are used for exhausting, evacuating and priming applications using operating steam or air in sizes from ½” to 12”.

Models U and L are single-stage ejectors which use steam as the operating medium. They are available in 16 capacities and suction sizes from 1” to 4”.
The 2NC is a two-stage steam operated ejector with the same range of capacities and sizes as the U and L.

What is a Jet Pump?

Penberthy Jet Pumps are a kind of jet-type pump that do not require any moving parts to be able to pump out a liquid or gas from a certain area. These pumps make use of their structure to transfer energy from one fluid to another via the Venturi effect. The structure of the pump is such that it has an injector chamber with a narrow shaped nozzle or tapered jet that is located inside the chamber and points axially towards the exhaust chamber to increase the pressure of the motive fluid as it enters the eductor. At the bottom of this nozzle is an opening that is used to suck in any form of fluid or other substance that needs to be extracted from a certain environment. The suction happens due to Venturi effect that creates a drop in pressure at the tip of the nozzle due to the fast flowing motive fluid which has gained kinetic energy due to the tapered shape of the nozzle. This difference in pressure causes the desired fluid to be sucked into the eductor and mixed into the flow stream to be guided out of the eductor.

All jet pumps operate on the principle of a fluid entraining a second fluid. Although design and construction may vary, this applies to all jet pumps.

All jet pumps have three common features: inlet, suction and discharge.

They function as follows:

Inlet – The operating medium (liquid, steam or air) under pressure enters the inlet and travels through the nozzle into the suction chamber. The nozzle converts the pressure of the operating medium into a high velocity stream, which passes from the discharge side of the inlet nozzle.

Suction – Pumping action begins when vapor, gases or liquid in the suction chamber are entrained by the high velocity stream emerging from the inlet nozzle, lowering the pressure in the suction chamber. The resulting action causes the liquid, gas or vapor in the suction chamber to flow toward the discharge.

Discharge – The entrained material from the suction system mixes with the operating medium and acquires part of its energy in the parallel section. In the diffuser section, part of the velocity of the mixture is converted to a pressure greater than the suction pressure, but lower than the operating medium pressure.
