For example: TWN 5636 (1000 RPM), LW 2020 (1450 RPM), HWD 4040 (3400 RPM).
A K, preceded by a dash (LW-K, ZW-K), means the pump features a built-in pressure unloader/regulation valve
(e.g.: LWR-K 2020, ZW-K 4022). This rule does not apply to the AX and BX models because these already
feature built-in pressure unloader/regulation valves.
The model code numbers allow determining max flow rate and pressure.
By means of the first two figures (if the number consists of four figures) or by means of the first three figures
(if the number consists of five figures) the max flow rate can be determined according to the following table:
Max flow rate in l/min = first two (or three) figures x 0.378
Max flow rate in USgpm = first two (or three) figures : 10
