Whale Marine Gulper MK2 12V Toilet Pump - Reliable Waste Evacuation for Marine Applications - BP2652B

Whale Marine Gulper MK2 12V Toilet Pump (BP2652B)

The Whale Marine Gulper MK2 12V Toilet Pump (BP2652B) is a purpose-built 12V waste management pump designed specifically for the rigors of marine toilet evacuation. Renowned for its "non-clog" diaphragm technology, the Gulper MK2 is the industry benchmark for reliability, capable of handling unmacerated waste and hair without the risk of burning out a motor—a common failure point in traditional impeller-based macerator pumps.

The "No-Clog" Advantage

Unlike centrifugal macerator pumps that use high-speed blades to shred waste, the Gulper MK2 uses a large-diameter diaphragm and robust non-choke valves. This mechanical action allows the pump to pass large solids and debris easily. It is particularly valued in marine applications because it can run dry without damage, meaning you don't have to worry about the pump overheating once the holding tank or head is empty.

Key Features:

• Non-Choke Valve Technology: Large, smooth-bore valves ensure that waste passes through the pump without snagging or causing blockages.

• Dry-Running Capability: The diaphragm design allows the pump to run dry indefinitely, providing peace of mind during the evacuation process.

• Dual Action Pumping: Features a powerful suction lift that can be mounted up to 9.8ft (3m) above the waste source.

• Easy Maintenance: The pump head can be rotated 360°, allowing for flexible installation in cramped engine rooms or behind bulkheads. The valves are easily accessible for cleaning if necessary.

• Low Power Consumption: Efficient 12V motor draws significantly less current than high-speed macerators, preserving your battery bank.

• Reliable Performance: Built with marine-grade materials to resist corrosion and chemical damage from toilet treatments.

Why Choose the Whale Gulper MK2?

The Whale Marine Gulper MK2 12V Toilet Pump BP2652B is the ideal solution for boaters who prioritize reliability over sheer speed. While it may pump slower than a high-RPM macerator, its ability to handle "real-world" waste without clogging makes it the far superior choice for long-distance cruisers and liveaboards. It is widely considered the most dependable waste pump in the marine market.

Installation Pro-Tip:

To ensure the longest life for your Gulper MK2, install it with the pump head positioned below the motor if possible; this prevents any potential leaks from reaching the motor housing. Additionally, while the pump can handle solids, always use marine-grade 1-1/2" sanitation hose to prevent permeate odors from escaping into the cabin over time.
