Intelligent Control (IC) Technology

The "brain" of the system is the solid-state sensor integrated into the tank lid.

• Automatic Operation: The sensor detects when water reaches a specific level and triggers the pump to empty the tank.

• Reliability: With no moving parts to clog or corrode, the sensor is much more durable than traditional float switches in the harsh grey waste environment.

• Triple Seal Protection: The lid features a unique seal that isolates the electronics from moisture and debris.

Key Features

• Compact "Space-Saver" Design: The 8L tank is small enough to fit into tight bilge areas or under cabin soles.

• Gulper 220 Pump: Included in the GK1512 kit, this pump is legendary for its non-choke valve technology. It easily handles hair and gels without the need for a filter.

• Multi-Port Versatility: The tank features multiple inlet and outlet port options (19mm, 25mm, and 38mm) to accommodate various plumbing layouts.

• 12V/24V Compatibility: The sensor can handle up to 20 Amps, allowing it to connect directly to any 12V or 24V pump system without a separate relay.

• Clear Inspection Lid: Allows for quick visual checks of the tank’s status without opening the system.

Applications

• Marine grey waste systems (sinks, showers, wet areas)

• RV and camper sanitation waste handling

• Sanitation upgrades and new installations

• Smart monitoring for onboard wastewater management

Installation Pro-Tip:

To minimize noise on board, you can choose to mount the Gulper pump remotely (up to 3 meters away from the tank) rather than directly on the tank side. This allows you to place the pump in a sound-insulated area or away from sleeping quarters while the compact tank stays tucked under the shower or sink.
