Functional engineering application
OVERVIEW The LEO LDP20 is an industrial-grade 3.1kW (4.2HP) 2-inch diesel engine clean water transfer 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 aluminum impeller, the LDP20 efficiently converts mechanical shaft energy into hydraulic velocity and static pressure. With a maximum discharge head of 28 meters and peak throughput of 28.0 m3/h (466 L/min), the unit provides dependable pressure delivery. Port dimensions of 2" G (50mm) suction and 2" G (50mm) discharge ensure smooth fluid velocity with minimal internal friction loss. CONSTRUCTION, MATERIALS AND MOTOR SPECIFICATIONS - Pump Body: Die-Cast Aluminum Pump Body with Heavy Tubular Frame with electro-deposition anti-rust coating - Impeller: Cast Aluminum Impeller engineered for wear resistance - Mechanical Seal: Silicon Carbide Mechanical Seal providing positive shaft sealing without fluid weeping - Motor: Continuous duty induction motor (Air-Cooled 4-Stroke Direct Injection Diesel), Class B 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 2" G (50mm) 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 Air-Cooled 4-Stroke Direct Injection Diesel 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.
