Product Overview

Most of our QX table steps through 1.5, 3, 6 and 10 m³/h. QX7-20-0.75S is the one model at 7 m³/h, and it is useful when your duty falls between the 6 and 10 m³/h lines.

Model	Flow (m³/h)	Head (m)	Power (kW)	Outlet (mm)
QX3-26-0.75S	3	26	0.75	25
QX7-20-0.75S	7	20	0.75	40
QX10-16-0.75S	10	16	0.75	50

All three use the same 0.75 kW motor. QX10-16-0.75S gives more water at less head, QX3-26-0.75S more head with less water, and QX7-20-0.75S sits in between. If you need about 7 m³/h and around 20 m, it is the better match, and a better match means lower running cost.

It has a 40 mm outlet, runs at 2900 r/min on 380 V and shares the series construction: precision cast stainless steel, fluororubber double mechanical seal, Class F motor with thermal protector.

There is no single-phase version of this model in the table.
