The HS430S Advanced FIT high-pressure aluminum pump from Wilden, part of PSG, a Dover company, is designed for applications that require high head pressures such as viscous and solids-laden slurries. Features include the FIT wetted path that minimizes the number of fasteners and allows for single socket reassembly for quicker, easier maintenance. The pump can be rested on its square flanges when performing field maintenance.

“Aluminum is our most popular material option,” says Tony Aguilar, sustaining engineer, Wilden. “It’s relatively inexpensive compared to other materials.”

A direct replacement for existing 1 1/2-inch high-pressure aluminum pumps, it requires no re-piping. The simplex design uses one liquid chamber to pump fluid and the other for pressure amplification. With a 2-1 pressure ratio, the pump can operate against a maximum of 240 psig discharge pressure without external boosters or amplifiers.

“This pump can be used almost anywhere you need to pump at relatively high pressure, or you have to deal with solids or higher viscosity liquids,” he says. “This particular pump can handle up to 1/4-inch solids.”

The pumps also feature the Pro-Flo SHIFT air distribution system for a 60 percent reduction in air consumption compared to other AODD pump technologies. 909/422-1730; www.wildenpump.com.
