5CP3110CSS: drive, frame size and accessories

Drive: At its rated point – 11.2 l/min at 250 bar – the 5CP3110CSS needs about 5.8 kW of drive power by the rule of thumb pressure × flow / 480; the next standard motor size above is 7.5 kW. Pumps of this frame size can be flange-mounted directly to a motor. The rated speed of 1,450 rpm suits a 4-pole standard motor (50 Hz). More under Sizing and drive.
Frame size: Frame size 5CP comprises 35 models covering 6.1–37.9 l/min and 100–275 bar. For more flow and more pressure see the 5CP4116CSS (11.9 l/min at 275 bar).
Accessories: Our catalogue has 7 pressure regulators, 15 unloader valves, 15 pressure relief valves and 1 pulsation dampener that suit 11.2 l/min and 250 bar. The lists are filtered to this operating point.
