Functional principle - Vertical centrifugal pumps

The impeller is connected over the shaft with the direct-drive electric motor. It rotates at a preset speed and produces a centrifugal effect (suction on the inlet and discharge on the outlet).

Flexible coupling

The coupling is a flexible and homokinetic coupling that assures the best performance in relation to the physical space occupied in its class.

It has a very compact design and allows safe power transmission by absorbing peak loads and torsional vibrations. Moreover, the elastic design of the polyurethane gear ring compensates for angular and radial misalignments and also absorbs small shaft length variations.


Vertical centrifugal pump is especially suitable for high aggressive media like acids and alkalies.

JP-830 vertical centrifugal pumps are high performance pumps for fixed installations with the pump immersed directly in the tank.

These pumps are used to quickly empty the fluid, with flow rates ranging from 6 to 38 m3/h. The special semi-opened impeller design, allows continuous pumping even with dirty fluids with apparent viscosity up to 500 mPas and small suspended solids.

JP-830 are electric motor driven pumps that, through a flexible coupling, transmitting the rotation to the shaft and the impeller, due to centrifugal effect, creates a suction on the central duct and a delivery on the peripheral tube.

Installation - dry running:

Suitable devices should be filled to prevent dry running and the formation of a vortex and possible air suction. Running dry or with air bubbles can cause damage to the pump.
