5CP4116CSS: drive, frame size and accessories

Drive: At its rated point – 11.9 l/min at 275 bar – the 5CP4116CSS needs about 6.8 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 see the 5CP4118CSS (13.2 l/min at 275 bar); none reaches a higher pressure.
Accessories: Our catalogue has 7 pressure regulators, 13 unloader valves, 15 pressure relief valves and 1 pulsation dampener that suit 11.9 l/min and 275 bar. The lists are filtered to this operating point.
