Product Overview

BenefitsDesign Features Downloads & Links

The SumpMaster is a sturdy sump valve designed to prevent product flow onto external floating roofs from drain system failures. The SumpMaster addresses several problems with traditional check valves, including more effective sealing at the potentially lower pressures encountered during a drain system failure, and not restricting drain flow rates calculated during the design of the floating roof.

Benefits

Backflow prevention and peace of mind

The SumpMaster keeps your floating roof protected from product backflow in the event of drain system failure.

Maintenance-free

Corrosion-resistant, stainless steel construction; withstands corrosive environments; no maintenance required

Superior sealing capability

In the event of product backflow, the SumpMaster will seal more effectively than traditional systems. Over time, metallic-ball systems develop surface irregularities from constant movement and impacts, resulting in an uneven sealing surface. The nonmetallic ball of the SumpMaster will not wear or dent, maintaining excellent sealing capabilities for the life of the tank.

Fast and easy installation

Easy bolt-on/bolt-off flanges

Custom-designed options available

SumpMaster can be fit with the customer’s choice of flanges

Buoyant check ball for excellent sealing at low pressures

Designed to operate effectively at very low backflow pressures as opposed to the higher pressures required by traditional check valves

Vacuum release feature

Vacuum release allows the check ball to release in the event rainwater backs up inside the sump. When the drain line is opened from below, the ball is allowed to fall and the roof is allowed to drain.

Nonmetallic check ball

For superior wear and corrosion resistance

Stainless steel housing

Stainless steel construction for superior wear and corrosion resistance

Debris guard cage

A unique stainless steel cage keeps the SumpMaster free of debris.

Multiple fitting options

Can be vertical or horizontal
