The Lowara 16GS15 pump end is a multi-stage hydraulic wet end designed for borehole extraction in the e-GS range. Starting operation requires coupling the unit with a 1.5 kW (2.0 HP) motor. Standard structural configuration allows vertical mounting or horizontal deployment.
The pump end uses a stainless steel external casing to prevent corrosion. The floating impeller system incorporates 8 stages fabricated from wear-resistant polymer. This multi-stage setup handles suspended sand up to a maximum of 150 grams per cubic meter.
Coupled with the required 1.5 kW motor drawing a nominal current of 10.5 Amps on 240 V single-phase supply, the pump end achieves a maximum head of 30.6 m. This system provides a maximum flow of 367 L/Min via its Rp 2" (50 mm) connection. Operating curves are fully validated.
This borehole pump end is specified for water temperatures up to 35°C. The unit is specified for deep immersion up to 150 meters with a 4OS motor or 300 meters with an L4C motor. Horizontal operation is possible with 4OS motors up to 2.2 kW and L4C motors up to 7.5 kW. The multi-stage design requires proper coupling with standard motors to maintain correct performance under standard system heads.
FEATURES- Features 8 multi-stage floating impellers to drastically limit wear and abrasion from suspended sand particles.
- Constructed with a sturdy stainless steel outer sleeve to limit corrosion and protect internal hydraulic components.
- Includes an integrated stainless steel strainer to filter out oversized particles and prevent debris entry.
- Features a hexagonal pump shaft design that distributes mechanical torque without vulnerable keyed joints.
- The upper and lower brackets are made of precision-cast stainless steel to establish a sturdy motor coupling.
- ErP/Ecodesign compliant in accordance with strict European Minimum Efficiency Index of 0.40 or higher.
- Suitable for continuous submerged operations in liquid temperatures reaching up to a maximum of 35°C.
