Venturi Jet Pumps Ltd. manufactures a wide range of venturi process equipment to suit almost any industrial process application. Our products primarily serve the power, chemical, petrochemical, pulp & paper, food, water & waster water industries, however our equipment can be used almost anywhere that has pressurised gases or liquids available to provide the driving force necessary for our units to operate.
All of our products are designed in house by either theoretical calculations or are arrived at from prototype designs. Typically our standard materials of construction are carbon steel and stainless steel; however we regularly use exotic materials such as Duplex, Hastelloy, Titanium as well as various plastics such as PVC, polypropylene and PTFE. We can also provide units equipped with ceramic lining or internal surface hardening if the duty requires it.
With over 20 years experience in industry, V.J.P. is a leading manufacturer in Venturi Process Equipment.
Liquid & Water Jet Eductors
Liquid Jet Eductors use the kinetic energy of a motive liquid to entrain another liquid, completely mix the two, and then discharge the mixture against a counter pressure and are used in large numbers throughout industry for pumping and mixing operations.
Applications are so numerous, it is impossible to note all of them. General uses include lifting, pumping, mixing, and agitating of liquids as well as handling granular solids and slurries. Some of the typical applications can be seen below:
- Draining flooded cellars, Emptying tanks and sumps or bunds, Pumping and mixing operations in oil treating systems
- De-watering sand and coal barges, Introducing anti-knock fluids and colouring matter into gasoline
- Continuous blending, Acidifying, Causticizing of oils, Mixing drilling mud, Producing emulsions
- Pumping food products, Pumping sand and filter clay or activated carbon
- Tank mixing, and various Proportioning operations
Liquid jet eductors consist of three basic components, namely a converging nozzle, a diffuser (or venturi), and a body to hold these parts in their relative positions and to provide a suction (or mixing) chamber. In addition, they can be equipped with accessories such as regulating spindles, snap valves and floats to control operation. When designing eductors experience is all-important to correctly design the nozzle, diffuser, and body and their relative positions as they are all highly critical and vary according to the physical properties of the liquids being handled.
Hopper Eductors
The Hopper Eductor is a hopper equipped jet ejector designed to entrain and mix granular solids or slurries with liquid and discharge the mixture to a receptacle or transfer it to a desired location. Originally developed to mix drilling mud for oil industry applications, these devices have proved to be so effective and versatile that they are being applied in increasing numbers in diverse industries including the food, chemical processing, pharmaceutical, glass, water treatment, and power to name but a few.
Hopper Eductors are also used extensively for ejecting sludge's from tank bottoms, for pumping sand from filter beds and for washing and conveying granular materials.
Optional wash down nozzles can also be mounted at the top of the hopper to help prevent the material from adhering to the sides of the hopper by continually wetting the hopper walls, this also helps to more easily move the materials down in to the eductor. Wash down nozzle are particularly effective when the material easily bridges or if a large quantity of material is being added, and can also help to reduce dust clouds forming when used with fine powders.
Tank Mixing Eductors
Tank Mixing Eductors are used to agitate liquid, dissolve powdered solids in liquid, and to mix two or more liquids intimately within a tank or other vessel without the use of baffles or moving parts inside the tank. These units can be used in the place of mechanical agitators.
Liquid Jet Exhausters
Liquid Jet Exhausters are simple, efficient and versatile devices for vacuum pumping or mixing liquids and gases. Using liquid under pressure as the only motive force, these units are ideal for handling mixtures or condensable and non-condensable gases.
Exhausters are manufactured in two varieties, a Single Nozzle Exhauster and a Multi Nozzle Exhauster. Single nozzle exhausters are standard units, and are similar in design to the Liquid Jet Eductor. Multi nozzle exhausters have much higher air or vapor handling capacities at lower pressures and are ideal where the motive liquid supply is limited.
No other pumping & mixing devices offer all these outstanding features:
Low Cost - Units are small in relation to the work they do and cost is correspondingly low.
Self Priming - Eductors are self-priming. They operate equally well in continuous or intermittent service.
No Moving Parts - Eductors are exceedingly simple and reliable. There are no moving parts to wear or break in a basic eductor. Even when equipped with accessories such as regulating spindles, snap valves, float mechanisms, they require little attention, only periodic inspection and maintenance.
Corrosion and Erosion Resistant - Because they can be made of practically any workable material, or coated with corrosion-resistant materials, eductors can be made highly resistant to the actions of the liquids handled or the environment in which located.
Safe - Eductors can be used in hazardous locations where electrically operated alternates would require explosion proofing at considerable cost.
Versatile - Various piping arrangements permit adapting to environmental conditions. Eductors of various types can handle granular solids, semi-solids, and slurries without contamination.
Automatically Controlled - Units can be adapted for automatic control by means of a pressure liquid regulating spindle or a snap-valve and float arrangement.
Perform Double Duty - Eductors mix motive and suction liquids intimately while pumping against a counter pressure.
Easy to Install - Connections can be made to suit your piping requirements. Little space is required to accommodate units and they are normally so light in weight they can be supported by the piping to which they are attached.
