Pipeline pumps are sold under many names. One recent order arrived as a list written with GD and SGR model names, each with a duty in brackets. The job was to match every line to a pump in our range without changing the duty.

| GD(2)40-15, 1.1 kW, vertical, 11 m³/h, 10 m, water | ISG40-100(I), 1.1 kW | Cast iron |
| SGR50-125, vertical, 12.5 m³/h, 20 m, hot water | SGR50-125, 1.5 kW | Cast iron |
