Functional engineering application
OVERVIEW The LEO 4XRm2/9-0.37 is an industrial-grade 0.37kW (0.5HP) 4-inch submersible borehole pump designed for rigorous water handling operations across Kenyan industrial, commercial, and agricultural facilities. Engineered with precision hydraulic clearances and high-grade metallurgical components, this pump ensures stable hydraulic throughput, low acoustic signature, and long service life under fluctuating operating conditions. OPERATING PRINCIPLES AND HYDRAULIC DESIGN Equipped with an optimized high-grade pom floating impellers (9 stages), the 4XRm2/9-0.37 efficiently converts mechanical shaft energy into hydraulic velocity and static pressure. With a maximum discharge head of 64 meters and peak throughput of 3.0 m3/h (50 L/min), the unit provides dependable pressure delivery. Port dimensions of 1¼" G suction and 1¼" G discharge ensure smooth fluid velocity with minimal internal friction loss. CONSTRUCTION, MATERIALS AND MOTOR SPECIFICATIONS - Pump Body: AISI 304 Stainless Steel Sleeve & Motor Casing with electro-deposition anti-rust coating - Impeller: High-Grade POM Floating Impellers (9 Stages) engineered for wear resistance - Mechanical Seal: Mechanical Seal with Sand-Guard Slinger providing positive shaft sealing without fluid weeping - Motor: Continuous duty induction motor (220-240V, 50Hz, 1-Phase), Class B insulation, IP68 ingress protection - Integrated Protection: Built-in thermal overload cut-out on single-phase windings; external overload relay recommended on three-phase installations KENYAN APPLICATION AND INSTALLATION GUIDELINES In East African operational settings, correct plumbing and electrical installation are vital for pump longevity: 1. Suction Plumbing: Install rigid suction piping of at least 1¼" G diameter. For suction lift duties (up to 0m), always fit a high-integrity foot valve with stainless steel strainer screen to prevent loss of prime. 2. Electrical Protection: Wire the 220-240V, 50Hz, 1-Phase motor through a dedicated motor circuit breaker or contactor with calibrated thermal overload protection. On sites prone to voltage sags, fit an electronic under/over-voltage monitoring relay. 3. Priming: Completely fill the pump wet end and suction line with clean water through the top priming plug before energizing the motor. Never run the pump dry. 4. Foundation: Anchor the pump securely to a level concrete plinth with anti-vibration mountings to avoid pipe stress and bearing misalignment. PREVENTIVE MAINTENANCE AND STARNEX SPARES SUPPORT Inspect mechanical seal faces and shaft bearings every 2,000 running hours or semi-annually. Lubricate bearings where applicable and clean suction strainers periodically. STARNEX Industrial Spares maintains direct inventory of genuine LEO replacement seals, O-rings, impellers, capacitors, and terminal boxes at our Enterprise Road trade counter in Nairobi.

Common questions on this part
Engineered for standard 4-inch (100mm internal diameter) or larger drilled boreholes across Kenya, fitting comfortably with submersible drop cables and safety rope.
With a maximum shut-off head of 64 meters, it operates efficiently between 30 to 50 meters depth, delivering 15 to 30 liters per minute for rural homesteads and farm watering.
The multi-stage floating POM (polyoxymethylene) impellers and polycarbonate diffusers allow small sand grains (up to 150 g/m3 sand content) to pass through without seizing or binding the pump shaft.
Use waterproof 3-core 1.5mm² flat submersible drop cable with vulcanized resin-sealed splice joints.
Yes, supplied complete with an external starter control box containing the start/run capacitor and thermal overload reset switch.
