Wilfley’s heavy duty slurry pumps excel in the abrasive, high percent solid slurries found the in the aggregate industry
In It for the Long Haul
Commercial grade may suffice for certain automotive products and B2B markets, but aggregate production requirements rely on equipment designed for continuous, mission critical operation. Moreover, operational demands often subject industrial equipment to rigors well outside a fully constrained design window.
Although the majority (75-90%) of pump ownership costs can be attributed to issues with seals and bearings, the basic design of the pump has a lot to do with its long term success. Wilfley’s philosophy is to produce heavy duty pumps that provide maximum productivity in the harshest of conditions. For instance, our robust ASME B73.1 A9 chemical process pumps are up to 60% heavier than Tier 1 competitors. And a similar trend exists on rotating elements: a common shaft robustness index follows an L3/D4 format and the A9 pump is on average 55% stiffer than others.

Wilfley’s philosophy is that downtime is unacceptable, so we continue to build robust pumps for continuous, tough and critical services.
Toughness Where It Counts
Material excellence is central to our value proposition. The remarkable MAXALLOY® 5A hard iron delivers high value in extreme operating conditions like aggregate production, with hardness values exceeding 700 HBN (equivalent to 82.6 RA). In addition, MAXALLOY® 5A can handle a wider range of pH values, including the basic range of aggregate, than industry standard hard irons. These superior physical properties when combined with Wilfley’s heavy duty, singular wall design provide exceptional performance far beyond less competitive, thin layer liner designs.

The Environmental Edge
According to many estimates, industrial uses account for 20% of global water usage. As with any finite resource, efforts to reduce consumption will shift from goodwill, to economic requirement and eventually legislative restrictions. Although largely abundant (and recyclable), water is often taken for granted and used with little regard – including seal flush systems for the majority of centrifugal pumps in aggregate production.
Wilfley Sealing Technology effectively voids the outdated and preconditioned thought process on water-based, seal flush systems centric to friction-derivative face seals or compression packing rings. Traditional yet anachronistic sealing systems generate significant energy losses and subsequent heat which therefore require a means to moderate temperature and provide lubricity (usually via external water flush). In addition, the Wilfley seal eliminates the potential flush contaminant and therefore saves the otherwise wasteful energy and complex processes that must be deployed to remove it from the fluid product. Use the calculator below to see how much flush water you are currently using and the environmental impact that is associated with it.
