LEO LVR2-22 2.2kW (3.0HP) 22-Stage Extra-High-Pressure Vertical Pump

OVERVIEW The LEO LVR2-22 is an industrial-grade 2.2kW (3.0HP) 22-stage extra-high-pressure vertical 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 aisi 304 stainless steel impellers (22 stages), the LVR2-22 efficiently converts mechanical shaft energy into hydraulic velocity and static pressure. With a maximum discharge head of 197 meters and peak throughput of 2.0 m3/h (33.3 L/min), the unit provides dependable pressure delivery. Port dimensions of DN25 / DN32 suction and DN25 / DN32 discharge ensure smooth fluid velocity with minimal internal friction loss. CONSTRUCTION, MATERIALS AND MOTOR SPECIFICATIONS - Pump Body: Cast Iron Base with AISI 304 Chamber Casing with electro-deposition anti-rust coating - Impeller: AISI 304 Stainless Steel Impellers (22 Stages) engineered for wear resistance - Mechanical Seal: Silicon Carbide / Carbon / Viton providing positive shaft sealing without fluid weeping - Motor: Continuous duty induction motor (380-415V, 50Hz, 3-Phase), Class F insulation, IP55 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 DN25 / DN32 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 380-415V, 50Hz, 3-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.
