Flow and head capabilities

A single stage pump will generate a head of 4 to 6 meters running at low speeds. Higher heads, up to 100m for the smaller pumps, are achieved by using multiple stages and/or higher speeds. The large pumps are capable of flows of up to 2600 litres per second.


Power pumps

The largest helical rotor power pump range in the world.

Characteristics and features

  • Positive displacement, with flow proportional to speed.
  • Pressure head independent of pump speed.
  • Very high efficiency over a broad range of heads and speeds reduces fuel/electricity consumption.
  • Resistant to mild abrasion.


The power pump range is suitable for high flow and high head water transfer duties, spray irrigation, stock watering, domestic water supply, and water abstraction from saturated river beds.

Flow and head capabilities

Orbit’s range of power pumps for water applications is suitable for flow rates of up to 95m3 per hour and discharge pressures of up to 30 Bar.


Dosing pumps

Orbit are the approved distributors for these pumps in southern Africa which are renowned for their high accuracy and supreme quality.

Jesco is dedicated to create and to maintain a high standard for the quality of the environment and life worldwide, with a special focus on water treatment. This is achieved by innovative solutions for municipal and industrial applications in the area of water, waste water and process technology. Our products incorporate Jesco know-how; they are the heart of each metering system.

Diaphragm pumps

Diaphragm metering pumps are leakage-free and especially suitable for corrosive or toxic media.

Depending on the type of gear, the diaphragm can be used at pressures of up to 10 bar. As a standard, diaphragm pumps are fitted with a separation chamber which, in the event of a diaphragm failure due to wear, prevents the medium from flooding the pump itself or other system components. Any leakage is routed through an outlet pipe to a collection tank. Flow capabilities range from 2,4 l/hr to 4000 l/hr with a maximum pressure of up to 10 Bar.

The diaphragm metering pumps are also available in a double-diaphragm configuration.

Piston pumps

Piston pumps are precise metering devices and relatively independent of the back-pressure. In contrast to diaphragm pumps, the metering capacity changes in proportion to the stroke length and can be reproduced, even if very small quantities are required.

Therefore, double or multiple-head piston pumps are particularly suitable for precise mixing of different media at a freely settable, constant ratio. By using controllable driving motors, the overall capacity can be changed infinitely between 5 and 100% while the ratio remains constant. Depending on the version, KARDOS pumps can be equipped with 1 to 12 heads.

The piston dosing pumps have a flow capability of up to 8200 l/hr with pressure up to 400 Bar.

Borehole pumps

This pump comprises a single helical rotor that rotates eccentrically within an elastomeric stator of double helical form.

Characteristics and features

  • Positive displacement, with flow proportional to speed.
  • Efficient over a broad range of heads and speeds; pressure head independent of pump speed.
  • Double spider bearing in pump element prevents driveshaft stresses; rubber stabilisers eliminate noise and vibration.
  • Resistant to mild abrasion.
  • Discharge head suitable for drive by AC/DC/solar electric motor, petrol or diesel engine, tractor or rotary windmill.

Flow and head capabilities

The range of borehole pumps is suitable for installation depths of down to 400m with the GW1306 and flow rates of up to 170m3 per hour with the GW25002.

Viscous Liquid Pumps Co. was established in the early 1970’s and became a professional trademark in domestic and foreign markets.

Internal eccentric gear, spur gear, helicial gear, external driven helical gear, vane type pumps which are own production of Vimpi, can be used in maximum efficiency for pumping all types of viscous and semi viscous liquids by modifying the materials of pump items according to usage purpose. Becuase of their positive displacement characteristic, Vimpi pumps can reach higher pressure even at low rounds by sucking from 6,5m depth due to the vaporization point of the liquid. Vimpi pumps have ability to turn both of the two sides by changing round direction of the pump shaft. If the pump selection and necessary maintenance is done correctly, Vimpi pumps will serve for a long time.

On the other hand, centrifugal pump, reducer, blower, burner, potable emulsion mill are existing in Vimpi product range. Also, in specific working benches, spur, helical, rack, internal gear machining, turning, million and grinding can be done for the industry.

The main principles for Vimpi are making new designs of the products for higher quality, controlling each of the production processes, delivering on time, increasing the customer satisfaction by supporting with large spare parts and technical service after sales.
