Functional engineering application
OVERVIEW The LEO 4DWP100-0.75 is an industrial-grade 0.75kW (1.0HP) 4-inch deep well helical rotor submersible 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 helical rotor / rubber stator, the 4DWP100-0.75 efficiently converts mechanical shaft energy into hydraulic velocity and static pressure. With a maximum discharge head of 75 meters and peak throughput of 1.8 m3/h (30 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: AISI 304 Stainless Steel Casing with electro-deposition anti-rust coating - Impeller: Stainless Steel Helical Rotor / Rubber Stator engineered for wear resistance - Mechanical Seal: Mechanical Seal with Sand-Guard Slinger providing positive shaft sealing without fluid weeping - Motor: Continuous duty induction motor (220-240V, 50Hz, 1-Phase), Class B insulation, IP68 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 0m), 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 4DWP uses a progressive cavity helical screw rotor inside a rubber stator, generating high pressure at low flow rates with excellent energy efficiency.
Delivers up to 75 meters head and 1.8 m3/h (30 L/min) flow on 0.75kW power, ideal for low-yielding boreholes in Kenya.
It extracts water at a steady 20-25 L/min rate without drawing down the water table too rapidly, preventing borehole dry-out.
Use 1-inch (25mm) Class 10/16 HDPE pipe.
