The GR range includes 'jet centrifugal' and regenerative pumps in corrosion-resistant bronze, with close-coupled electric motors. 

GR regenerative pumps develop substantially higher heads than can be attained by small centrifugal pumps.

Performance:
Self-priming regenerative pumps with DC motors:
- Flow rates from 2 to 250l/min  (0.4 to 55 gallons/minute)
- Heads up to 33m (100ft)

GR self-priming jet-centrifugal pumps are exceptionally quiet running, and are a popular choice for pressurised water systems in large sailing yachts, motor cruisers and workboats.  See also 'Aqua Major Pumps'

Performance
- GR jet centrifugal pumps with AC and DC electric motors
- Flow rates from 20  to 160l/min (4.4 to 35 gallons/minute)
- Pressures up to 5bar (70psi)

Larger GR-series multistage bronze pumps generate heads up to 200m (pressures up to 20 bar), and are well suited to pressure-boosting and fire emergency duties.  Contact us for details.
