Single and multi-stage vertical pumps

Roto vertical pumps are designed to operate with the pump elements submerged in the medium. These pumps are specially designed to vary the column length to suit sump depth. The strainer can be fixed in the suction port to prevent large solids from entering the pump. Pumps are only available in close-coupled configurations with different construction materials and shaft seal options. These pumps are compact and space-saving.

​Media: Sticky, abrasive, viscous, complicated media.

​Advantages: Pumped gently without any impact on the structure.

– High precision at low rpm

- Self-priming pump, which means that the pump offers good properties

- Very good operational reliability

– Normal low pulsation at pressure difference, capacity and dry matter content


– Capacity: Up to 500 m3/h

– Working pressure: 12 bar



Horizontal internally stored Twin Screw Pumps are chosen where the fluids are clean and have lubricating properties. These pumps are designed with internal bearings that are lubricated by the pump medium itself. The suction and discharge ports are in-line.

The mechanical seals are supplied as standard scope of delivery. Gland packing option can also be offered as per application requirements. These pumps are equipped with relief valves and are suitable for 100 % bypasses. These pumps are also available in standard foot-mounted configuration with sump heating as an option.

Characteristics and benefits:

Standard API676

Long and trouble-free service life due to the absence of metal-to-metal contact between the pump elements. It can even go dry for a limited period of time.
No axial thrust Dual flow of fluid in opposite direction balances axial thrust.
Higher volumetric efficiency due to special double profile of screw flanks.
High cavitation-free suction lift due to low NPSH (R).
Broader compliance with API 676, 2nd edition.
Self-priming and capable of handling trapped air/vapour/gas due to positive displacement action and is inherently self-priming.
Uniform Metered Flow Being a positive displacement pump, head is independent of speed and capacity is approximately proportional to speed.
Capable of handling a wide range of fluids, lubricating/non-lubricating as well as aggressive fluids can be handled due to the choice of different designs and materials of construction.
Safe to operate has built in relief valve, designed to bypass up to 100 % capacity.
