The 1 inch plastic Wilden pumps show a trade-off that is easy to miss if you only look at maximum flow. The bolted P200 moves more liquid. The clamped P2 lifts much further.

Which matters for your duty
Pumping out of a pit, sump or tanker from above: the P2’s 28 ft (8.5 m) dry lift, the highest of any Wilden page we have checked, gives real margin
Flooded suction from a tank, where flow is the priority: the P200 delivers about half as much again
Liquids with small particles: the P200 passes slightly larger solids
Both have ANSI flanged ports on all but two builds, which makes them straightforward to fit into plastic process pipework. PTFE diaphragms are the most common choice on both, with Santoprene second.
Suction lift falls with heavier or hotter liquids, so treat the dry figures as best case and tell us the real conditions when you ask for a recommendation.
