LEO AJm75 0.75kW (1.0HP) High-Performance Self-Priming Jet Pump

OVERVIEW The LEO AJm75 is an industrial-grade 0.75kW (1.0HP) high-performance self-priming jet 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 stainless steel aisi 304 impeller, the AJm75 efficiently converts mechanical shaft energy into hydraulic velocity and static pressure. With a maximum discharge head of 50 meters and peak throughput of 3.6 m3/h (60 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: Stainless Steel AISI 304 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), IP44 insulation, Class F 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.
