Super-XL Pump
The Simplex Super-XL Pump
is a high-tech hydraulic pump featuring pressure-loaded, self-compensating
gears and a mechanical shaft seal. These precision gears are
enclosed by a high strength, die cast aluminum center section.
The Super-XL Pump is designed for applications where the
pump starts and stops on demand (ie. automatic tank refilling)
and for high pressure applications up to 2500 PSI. Viscosity
range is up to 1000 SSU. Do not use this pump for applications
that are noise sensitive.

Series 420 Pump
The Simplex Series 420 Pump
is an internal gear rotary pump precisely machined and assembled
with only two moving parts. This pump achieves and retains its
reliability over a wider range of viscosities and is much quieter
than other pump designs. Pumping action is based on a rotor,
idler gear and crescent-shaped partition cast integral with the
cover. Optional automatic reversing is available.
The Series 420 Pump is designed for continuous duty applications
where the pump runs nonstop for extended periods, for boiler
feed loop applications, for noise sensitive applications, and
for many other industrial pump applications. Viscosity range
is up to 5000 SSU or greater when slower speed motors are used.
