SUBMERSIBLE SOLAR PUMP SET
Solar pumps fitted with PMSM submersible motors will start discharging water earlier in the day and will work for longer hours as compared to pumps fitted with AC motors - resulting in significantly more water delivery during the day.
Motors run at synchronous speed (zero slip) and are about 10%-15% more efficient than equivalent AC Induction Motors; thus delivering real, tangible benefits in solar pumping systems.
High-efficiency PMSM submersible motors are made with high-grade stainless steel.
PRODUCT BENEFITS
- Large increase in efficiency and compact size compared to AC submersible motors
- Lowest energy costs due to high efficiency & power factor even under partial load conditions.
- Excellent value for money solution for solar pumping applications due to higher water output for a given a number of solar panels.
- Lower system cost for a given head & flow requirement (it may be possible to eliminate one solar panel or use cheaper panels with lower energy output)
SUBMERSIBLE MOTOR SPECIFICATIONS:
- IP68 grade protection
- Stainless steel casing, shaft & other components
- Equipped with mechanical seal and sand guard for maximum sand protection
- Insulation Class F
