Product Description
The Whale BP9005 Gusher Urchin is one of the most trusted manual bilge pumps in the marine industry, known for its efficiency, rugged construction, and long service life. Designed for both bilge and waste water transfer, this versatile pump operates entirely by hand, eliminating reliance on electrical systems and ensuring reliable operation even in emergencies.
With an impressive pumping capacity, the Gusher Urchin can deliver 37.5 LPM (9.9 US GPM) at 45 strokes per minute and up to 55 LPM (14.5 US GPM) at 70 strokes per minute. It achieves a maximum suction lift of 4 metres (13.5 ft) and a discharge head of up to 3 metres (9.8 ft), making it ideal for medium to large vessels. The fixed handle design provides a sturdy grip and smooth action for continuous pumping.
Constructed from tough marine-grade materials, the pump body and diaphragm are designed to withstand long-term exposure to seawater and waste fluids. Its compact body—measuring 139mm high and 280mm long—is suitable for bulkhead or deck mounting, and it accepts both 25mm (1") and 38mm (1½") ID hoses for versatile installation options.
Manufactured in the United Kingdom, the Whale Gusher Urchin is trusted by sailors and boatbuilders worldwide. It meets ISO150831 approval as a primary bilge pump for vessels over 12 metres and is backed by Whale’s 5-year warranty, ensuring reliability and peace of mind for every voyage.
