vMAX™
Vertical cantilever pump

WE DISCOVER POTENTIAL
 Set it and forget it
A sump pump you can trust
We developed our vMAX line of vertical cantilever pumps for both conventional and
harsh sump and process duties that require reduced degradation of any pumped solids.
The fully recessed impeller design permits passing of large solids and operation without the need
for sump level control. The vMAX design provides reliable continuous operation, no required
impeller adjustments, less downtime, and simple maintenance.

 vMAX™
Metal Vertical Pump
Our vMAX line of vertical hard-metal pumps provide reliable operation even in the most
extreme conditions. The vMAX prevents solids from settling in the sump and delivers
continuous operation without sump level control. You truly can install it, set it, and forget it.

Designed to operate successfully under typical-to-extreme

sump pump duties, the vMAX delivers the following:

Prevents solids from settling in the sump

An agitator is not necessary to prevent solids from settling in the sump.
The vortex effect created by the vMAX pump's impeller creates enough
turbulence to keep the solids in suspension and the sump free of
sediment build-up.

No sump level control required

In conventional designs, when the sump level falls below the suction,
the pump loses its prime and the slurry comes rushing back down
the discharge pipe. Returning slurry impacts the rotating impeller
and cause violent vibrations which can lead to catastrophic failure.

With this problem in mind, we designed the vMAX pump to include

a fully recessed impeller. When the sump has been emptied of slurry,
the recessed impeller allows the slurry to return safely down the
discharge pipe without contacting the impeller.

The result? The vMAX operates without the need for sump level control.

 vMAX™-R
Rubber Lined Vertical Pump
The vMAX-R rubber lined cantilever pump has been developed for the most difficult
corrosive applications. Every part that could come into contact with the slurry
is elastomer lined to ensure reliability. With multiple materials options, the vMAX-R
is adaptable to many different acid and slurry temperature combinations.

Available in a range of corrosion resistant materials such

as natural rubber, neoprene, EPDM, and chlorobutyl.

Extended wear life

Our vMAX and vMAX-R pumps provide the best wear life for each
sump and process application. The vMAX-R handles corrosive
applications, while the vMAX covers conventional and extreme
duties - even with highly viscous slurries that contain large solids.
