Functional engineering application
OVERVIEW The LEO APSm37-AT is an industrial-grade 0.37kW (0.5HP) automatic self-priming peripheral booster 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 cast brass impeller, the APSm37-AT efficiently converts mechanical shaft energy into hydraulic velocity and static pressure. With a maximum discharge head of 38 meters and peak throughput of 2.1 m3/h (35 L/min), the unit provides dependable pressure delivery. Port dimensions of 1" G suction and 1" G discharge ensure smooth fluid velocity with minimal internal friction loss. CONSTRUCTION, MATERIALS AND MOTOR SPECIFICATIONS - Pump Body: HT200 Cast Iron with Built-in Check Valve with electro-deposition anti-rust coating - Impeller: Cast Brass Impeller engineered for wear resistance - Mechanical Seal: Carbon / Ceramic / NBR providing positive shaft sealing without fluid weeping - Motor: Continuous duty induction motor (220-240V, 50Hz, 1-Phase), Class F insulation, IP44 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 1" G diameter. For suction lift duties (up to 9m), 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
The APSm37-AT comes pre-assembled with a 2-liter pressure tank, an adjustable electromechanical pressure switch, and an integrated non-return check valve, turning on and off automatically based on tap demand.
Yes. Unlike standard peripheral pumps, the APSm series incorporates a specialized self-priming hydraulic channel that evacuates air from the suction line up to 9 meters suction lift.
The factory cut-in pressure is set at 1.4 bar and cut-out at 2.4 bar, providing comfortable, consistent domestic shower and tap pressure.
Check the Schrader valve air pressure every 6 months using a standard tire gauge. Maintain air pre-charge at approximately 0.2 bar below the pump cut-in pressure (around 1.2 bar).
Yes, our engineering team provides complete plumbing and electrical connection diagrams upon purchase to ensure reliable operation.
