Johnson Pump 2200 GPH Heavy Duty Bilge Pump (22004)

The Johnson Pump 22004 is a high-capacity, heavy-duty centrifugal bilge pump designed for the demanding requirements of commercial vessels and large yachts. Moving an impressive 2200 Gallons Per Hour, this 12V pump is built to provide maximum safety and rapid dewatering in the most challenging marine environments.

Industrial-Strength Reliability

Unlike standard consumer pumps, the 2200 series is engineered for durability. It features a high-torque, 12-pole motor with double ball bearings and a mechanical shaft seal. This professional-grade seal eliminates the shaft wear common in cheaper pumps and provides a superior barrier against moisture ingress.⁵ The motor is also liquid-cooled, utilizing the surrounding water to dissipate heat and extend the life of the pump during continuous operation.

Key Features:

• High-Volume 2200 GPH Output: Designed to handle significant water ingress, making it an ideal primary pump for offshore vessels.

• Mechanical Shaft Seal: Uses a carbon/ceramic mechanical seal for maximum protection against saltwater, significantly outlasting traditional lip seals.

• Threaded Discharge Port: Features a 1-1/8" threaded discharge, providing a secure, leak-proof connection for your bilge plumbing.

• Liquid-Cooled Motor: The motor housing allows water circulation to prevent overheating during long-duration pumping.

• Rugged Construction: Built with a high-impact ABS body and a corrosion-resistant SS316 stainless steel shaft.

• Universal Strainer Base: The snap-on base is easy to remove for cleaning or inspection without needing tools or disconnecting the plumbing.

• Ignition Protected: Fully compliant with USCG and ISO 8846 standards for installation in gasoline-powered engine compartments.

Why Choose the Johnson 2200 GPH?

The 22004 is a "pro-series" pump. It is the preferred choice for boaters who prioritize mechanical reliability over lower price points. Its ball-bearing motor and mechanical seal design mean it can handle the vibration and harsh conditions of an engine room far better than standard "cartridge" style pumps.

Installation Pro-Tip:

Since this pump uses a threaded discharge port, ensure you use a marine-grade thread sealant (like PTFE tape or a non-hardening pipe dope) to ensure a watertight connection. This prevents water from spraying back into the bilge from the hose connection under high pressure.
