Functional engineering application
OVERVIEW The LEO APm37 is an industrial-grade 0.37kW (0.5HP) peripheral clean water vortex 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 with anti-block inserts, the APm37 efficiently converts mechanical shaft energy into hydraulic velocity and static pressure. With a maximum discharge head of 40 meters and peak throughput of 2.4 m3/h (40 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 anti-rust electrophoresis with electro-deposition anti-rust coating - Impeller: Cast Brass with anti-block inserts 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 8m), 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 LEO APm37 delivers its optimal duty point between 20 to 30 meters of head, supplying approximately 15 to 25 liters per minute (0.9 to 1.5 m3/h). Its maximum shut-off head is 40 meters, making it ideal for domestic single-story and double-story roof tank boosting in Kenya.
Yes. The APm37 incorporates brass inserts integrated into the cast iron pump body face plate. This prevents copper-iron galvanic scaling and reduces the risk of the brass impeller jamming after prolonged idle periods during dry seasons.
Use a minimum 1-inch (25mm internal diameter) rigid HDPE or PPR pipe. For negative suction lift from underground tanks (up to 8 meters), fit a brass foot valve with a stainless steel mesh strainer to maintain prime.
Yes. Combining the APm37 with a digital or electromechanical pressure controller (such as the LEO PS-01A) creates an automatic pressure booster system that turns on instantly when a tap opens and cuts off on zero flow.
The APm37 motor includes internal thermal overload protection. For complete electrical safety against Kenya Power surges and under-voltage, wire it through a 6A MCB with a dedicated surge suppressor or voltage protector.
