KREBS® vMAX™ Vertical Slurry Pump

vMAX™ vertical slurry pumps prevent solids from settling in the sump
Our vMAX™ vertical slurry pump for sump and process applications easily handles both conventional and extreme duties – even with highly viscous fluids or slurries that contain large solids.

Key benefits

Set it and forget it – a sump pump you can trust day in, day out

Large solids passing size expand_more

With a large solid passing size, the vMAX prevents solids from settling at the bottom of the sump. The results? No blinding. No shutdown due to clogging.

Long wear life expand_more

Both metal and rubber options are available with our vMAX and vMAX-R Pumps to provide the best wear life for each application. The vMAX handles large solids applications, while the vMAX-R is well suited to corrosion-resistant and fine-solids abrasion applications.

No sump level control required expand_more

When the sump has been emptied of slurry, the fully recessed impeller design allows the solids to return down the discharge pipe without choking the pump. As the sump level rises, the vMAX will discharge the slurry until the level is below the suction pipe, at which point the slurry in the discharge pipe can return safely to the sump. In conventional sump pumps, the returning solids impact the impeller and cause violent vibrations which can lead to catastrophic failure.

Easy to operate, easy to maintain expand_more

No impeller adjustments required. No need for water flush. Operates without level control, if required. You truly can install it, set it and forget it.

Product Features

vMAX vertical pumps - make sump and plant floor clean-up a breeze!

The process of pumping fluids that contain large solids, or transferring highly viscous fluids, can be fraught with difficulties. Common problems with vertical sump pumps include build-up of solids at the suction inlet, leakage from the back of the casing, and excessive vibration.

The vMAX addresses these concerns with its improved hydraulic design. Its bottom-only suction configuration prevents solids from clogging the sump. The improved impeller design eliminates the vibration issues, while its high-performance expelling vanes on the back of the impeller shroud work to prevent leakage.

vMAX

The vMAX includes a suction strainer that works as a particulate filter to prevent large particles from entering the pump. A blinded or clogged strainer will ultimately lead to pump failure. To counter this, the vMAX Pump features an oversized suction-strainer surface area that prevents premature blinding and increases operational life, as it also eliminates the need to remove the pump for cleaning.

Designed to operate successfully under typical-to-extreme clean-up sump pump duties, the vMAX delivers the following:

Mining and mineral processing
Carbon transfer
Heavy-duty abrasive slurries
Continuous operation without sump level control
Large solids passing size
Reduced clogging and blinding, with subsequent required pump removal for cleaning

vMAX-R (rubber lined)

The vMAX-R Rubber Lined Cantilever Pump has been developed for the most difficult corrosive slurries with finer solids. Every part that could come into contact with the slurry is elastomer lined to ensure reliability. With multiple materials options, such as neoprene, EPDM, or chlorobutyl, the vMAX-R is adaptable to many different acid and slurry temperature combinations.

Product applications:

Mining processing
Dewatering
Chemical processing
Corrosive slurries
Power plants
Industrial processing

Additional features

The vMAX’s cantilever design does not require a stuffing box seal or submerged bearings.

The drive-end bearing is a fixed-clearance twin taper roller that provides axial thrust. The impeller-end bearing is a parallel roller design that delivers radial thrust. Bearings are grease-lubricated. A rigid 1040 steel shaft with large bearing span reduces shaft deflection and bearing loads.

An integral discharge elbow on the casing works to reduce localized wear.

With an integral mounting plate for supporting the pump above the sump, a steel discharge pipe extends above the liquid level, and is fixed to the mounting plate for access to your existing piping.

The adjustable motor mount is integral to the power frame assembly, and allows tension adjustment of the v-belt drive.

We provide a lifting yoke for crane hook suspension over the sump.

We offer pump sizes from 2-in (50 mm), 3-in (80 mm), 4-in (100 mm), 6-in (150 mm) and 8-in (200 mm), in submerged lengths of 4-ft (1.2 m), 5-ft (1.5 m), 6-ft (1.8 m) 7-ft (2.1 m), and 10-ft (3.0 m).
