Jabsco 50270-0311 24V Marine Electric Clutch Pump with Single B Pulley J50-158

Jabsco 50270-0311 24V Marine Electric Clutch Pump with Single B Pulley

Flexible-impeller pump driven from the main engine by belt and supplied pulley. Electrically operated clutch allows remote engagement. Neoprene impeller fitted as standard. Suitable for bilge, deckwash, ballast transfer and fire-fighting applications. Do not run dry. Heavy-duty spaced dual-bearing design with mechanical seal. Self-primes to 4.5m. Supplier notes 12V clutch and 2A pulley versions are available on request; this code is the listed 24V 1B version. The current supplier identifies this as a heavy-duty composite pump with spaced bearings and a mechanical seal. Confirm the exact housing material before choosing it where material compatibility is important.

Choosing and using this product

This pump is selected as part of an engine-driven installation, so port size is only one of the details to match. Check the drive arrangement, available shaft speed, mounting space and intended liquid before choosing a replacement. The pump's output depends on its rotational speed and the resistance of the connected system. A capacity quoted at a particular speed and head must not be treated as its delivery under every operating condition.

Plan the drive and plumbing together. The pulley or coupling must suit the actual shaft, belt arrangement and alignment, and the mounting needs to support the pump without forcing the pipework to carry its weight. Leave access for the cover, impeller and seal service work. Select fittings that match the stated connection standard; a BSP thread is not interchangeable with every other nominally similar pipe thread. Keep suction connections sound and the intake clear, following the manufacturer's recommendations for the intended service.

A flexible-impeller pump must not be allowed to run dry. Confirm that the inlet supply is available before engagement and follow the maker's priming and operating instructions. Check the impeller material against the liquid and temperature rather than assuming one impeller suits all fluids. For engine-cooling or other consequential service, have the complete installation and required duty checked by a competent marine technician. Inspect the system during commissioning for leaks, drive alignment and reliable delivery at the intended operating conditions. Retain the exact model and product code for ordering service parts, since similar-looking pumps can use different impellers, seals and port arrangements.
