DLQSB Planetary Gear Units for Submersible Pump (DLQSB690–DLQSB1465)
The DLQSB planetary gear unit sits between the submersible motor and the pump: the pump shaft engages the internal splines of the output planet carrier. Five sizes by flange diameter — 690, 930, 1050, 1150 and 1465 mm — for motors from 132–400 kW (DLQSB690) to 600–2,800 kW (DLQSB1465), motor speed 750–1,500 rpm, typical ratios 3.15–6.7. Sun and planet gears in carburized alloy steel, accuracy grade 5–6 to GB/T 10095-2001, splash lubrication. Resistive leakage and temperature sensors on both housing faces allow remote monitoring of the submerged unit.
Applications
- Submersible horizontal tubular (bulb) pumps
