Capacitor for JP 5 pump (Grun-183234)

Product Description

Run Capacitor 20 µF 400V/450V AC for Grundfos JP 5 Pump (Grun-183234)

The genuine high-performance run capacitor for Grundfos JP 5 pumps (part number Grun-183234) is engineered for single-phase electric motors driving booster set and water transfer pumps. Manufactured with self-healing polypropylene metalized film technology MKP (model MD MKP 20/285), this capacitor features a nominal capacitance of 20 µF (±5%). It delivers exceptional operational durability, offering up to 10,000 operating hours at 400V AC (Class B) and 3,000 hours at 450V AC (Class C) in compliance with the EN 60252-1 standard. Fitted with dual flexible lead wires, it guarantees quick and straightforward replacement inside the motor terminal box. Looking for additional pump components or system replacement parts?
