Grundfos Pump Saves Power
Last week up in cane country Tim Harvey (Townsville Branch Manager) drove to Ingham to commission a 42.4 kW Diesel Pump set with a Grundfos NKG 125 x 80 x 400/365 ISO spec end suction pump to irrigate Sugar Cane.
Previously the customer had been using PTO drive Southern Cross pumps powered by one of his tractors to irrigate using a significant amount of diesel per day. The new unit under operating conditions uses approximately 8 L/HR less than half of the tractor and with a fuel tank large enough to last 14 hours as they normally irrigate between 6pm – 6am when the wind is calm.
The customer requested 27 litres per second @ 77 m which is exactly what the pump set delivered at 2000 RPM as per our design.
