Product Overview
Civil excavations, municipal drainage lines, and food processing sumps deploy the Aussie GMP B4KQ-A/ST motor-driven unit for wide large-inch waste movement. A heavy channel-steel base plate delivers steady foundation anchoring under continuous plant cycles.
Pumping volume reaches an impressive 1,600 L/min open discharge at zero elevation, accompanied by a 14 m (20 PSI) shut-off head at zero flow. The heavy cast iron chamber houses an open trash-style impeller that clears suspended solids up to 37 mm with ease.
Electric shaft power is supplied by a 4 kW three-phase 415 V TEFC motor rated to IP55 enclosure protection, supplied unwired for direct plant switchboard wiring. Centrifugal self-priming action draws fluid from 6 m vertical depths without an intake foot valve.
Cast volute durability is protected by close-grained cast iron, a 316 stainless shaft, and a silicon carbide seal rated for 70°C liquid temperatures intermittently. A front clean-out cover unbolts easily for rapid de-silting. 3-year commercial GMP warranty coverage.

What solid particle clearance capability is engineered into the semi trash volute?
Large internal water passages on the Aussie Pumps GMP Semi-Trash B4KQ-A/ST (GB4KQ-A/ST 4KW) pass suspended solids, mulch, and stones up to 37 mm in diameter without restricting water movement.
What port threading and pipe coupling dimensions are cast into the volute?
Suction and delivery ports on the GB4KQ-A/ST 4KW incorporate four-inch female BSP threads, enabling connection to standard site transfer lines and camlocks.
How is mechanical power delivered to the pump shaft assembly?
Propulsion for the GB4KQ-A-ST-4KW is provided by a three-phase electric drive rated at 4 kW on 415 V line voltage, sealed within an IP55 terminal casing.
Is an external foot valve necessary to establish suction on incoming pipework?
No foot valve is required on the GB4KQ A ST 4KW on the suction line because internal chambers evacuate air to establish prime up to 6 m vertical depth.
What discharge volume capacity and maximum static head apply across the performance curve?
Peak volumetric displacement for the B4KQ-A/ST (GB4KQ-A/ST 4KW) reaches up to approximately 1600 L/min, with total elevation head developing up to approximately 14 m.
