STP Series

STP Self-Prime Trash Series

The STP Series is comprised of trash pumps and parts that are 100% interchangeable with the Gorman-Rupp Super T Series®. These self-priming trash pumps are a high solids handling, low maintenance series of pump.

The STP model is offered in sizes 2"–10", each equipped with an easily replaceable rotating assembly. The adjustable 4-bolt front cover can be removed to clear debris from the interior of the pump. Available in diesel or electric drive.

Priming notes

STP units are self-priming trash pumps: the casing holds a liquid charge that lets the pump re-prime on its own after the initial fill.

  • Prime the casing once at start-up; the retained charge lets the pump re-prime automatically afterwards.
  • Large solids-handling volute with a clean-out cover for field access to the impeller and wear plate.
  • Suction lift to roughly 25 ft with an airtight suction hose and foot valve where required.

Applications

Typical duty

  • Slurry and sludge transfer
  • Industrial process water
  • Quarry and mining sumps
  • Agricultural waste

Configuration options

  • Highway trailer, single-axle site trailer or bolt-down skid base
  • Diesel engine or electric motor drive
  • Critically silenced acoustic enclosure (~69 dBA at 30 ft)
  • Extended-run fuel cells and containment bases
  • Ductile iron wet end with open impeller for solids passage

Tell us your flow, total head and solids size and we will size the unit for you.

Performance

STP Performance Curves by Model
