The S4T-2 4-inch trash pump from Hydra-Tech Pump has integral stainless steel wear plates above and below the impeller. It fits into tight spaces and can be used as a submersible pump or a tank truck flange mount for direct loading or off-loading using onboard truck hydraulics. Requiring only 8 to 10 gpm of hydraulic flow at pressures to 2,500 psi, it is suited for operating with smaller hydraulic power units. It has a cast and machined hardened-aluminum volute, stainless steel wear plates for durability in a lighter package, and a two-vane open-channel impeller. Its stainless steel intermediate shaft has pressed-in-place upper and lower bearings attached to a gear motor with high-pressure lip seal, which combine to drive the two-vane open-channel impeller. It delivers output flows to 700 gpm, heads to 100 feet and pressure up to 2,000 psi.
