The SHP is a solar hydraulic pump intended for rural livestock farmers who need to pump to high heads typically (50-300m) from a surface water source. The motor is a brushless DC Smart Drive motor.
The SHP-triplex is a cost effective and reliable high lift solar pump. Theses are the main advantages:
Far more cost effective than the competition.
Far more efficient than the competition (world best in class, peak pumping efficiency 64%).
Do it yourself - No builder, electrician or water take permit needed (in NZ).
Light weight <20kg (no risk of lifting injuries) and 1 person can install it. Easy to move to a workshop for servicing.
Direct drive (no gearbox to add weight, cost and complexity).
High efficiency motor (up to 80% efficient).
Brushless motor (no brushes to wear out in the motor).
Electronic motor driver (up to 95% efficient) with MPPT (maximum power point tracking).
High efficiency plunger triplex pump (up to 85% efficient).
Slow running rpm (in the range 200-1200rpm) makes it quiet and durable.
Built tough for global export and fits into a DHL export carton.
Will pump to a set pressure (the point where the ball cock start to close) and then stop.
Pressure stop point is set via a simple push button. Default setting is 300 head and a 30 minute wait time.
Quality ceramic Triplex pumps last longer because each individual component does less work. The flow of water from a triplex pump is relatively constant so no pressure dampener is needed.
Can pump clean or dirty water (within reason) as plunger pumps are less prone to damage than piston pumps. The plunger does not run in a bore where abrasive grit can become trapped.
If the super-hard ceramic plungers are ever damaged they are low cost and quick to replace.
Is light enough to mount on a pontoon that floats on the surface of water of storage dams, lakes and river - eliminating the need for high suction lifts. Sucking water from more than 8m below the pump is problematic for all pumps.
The SHP-Triplex is available from May 2019. With the cost of solar PV falling to very low levels, solar PV water pumping makes a lot of sense for rural livestock farmers.
