Recessed Vortex Impeller Pumps

The WEMCO hydraulics

design reduces wear

The Vortex Principle

Impeller Types

Characteristics and

Advantages of the Vortex

The WEMCO recessed impeller has a curved

profile, which directs solids away from the volute

walls and on through the discharge, thereby

considerably reducing wear.

This exclusive concept, when associated with

tangential discharge, provides unequalled

resistance qualities and thus greatly reduces the

risk of choking.

In order to always offer the best solution to for

each application different types of impellers are

available.

The VORTEX technique developed by WEMCO is based on the principle of a whirlpool : a vortex is

created by the rotating recessed impeller, extending into the suction line, drawing the liquid / solids

into the pump and then quickly through the discharge whilst minimising fluid / solids contact with the

impeller and the volute.

This provides the WEMCO pump with a gentle pumping action and good resistance against wear with little

risk of plugging

Less chance of pump blockagesThe WEMCO vortex pumps are designed with the

impeller fully recessed in the volute casing

providing an unobstructed passage way between

suction and discharge allowing suction size solids,

whether soft, hard or fibrous to pass through the

pump without choking.

Extending pump lifeThe WEMCO pump has no close tolerances or

wear rings in the pump chamber and because the

majority of particles do not touch the impeller or

the volute, wear is reduced to a minimum. In

addition, with different material options available

the working life of the product can be further

extended.

Less MaintenanceSimply and robustly designed, the WEMCO pump

needs minimum maintenance, no special tools,

and no complex adjustments.
