Jabsco Par-Max HD6 Freshwater Delivery Pump, 6 GPM, IPX6

Overview

The Jabsco Par-Max HD6 is a freshwater delivery pump for on-demand marine water pressure systems, available in 12 VDC and 24 VDC versions with 40 PSI or 60 PSI pressure switch cut-off options. It delivers up to 6 GPM (22.7 LPM) open flow and uses a 5 chamber diaphragm pump design with quick connect ports.

This pump is made for pressurized freshwater service on board, such as supplying sinks, showers, galleys, and other fixtures from a tank-fed system. The integrated sealed pressure switch turns the pump on when the system calls for water and shuts it off when the selected cut-off pressure is reached.

Marine installation details are well covered: the pump has an internal bypass to reduce cycling, self-primes up to 7 ft (2.1 m) dry prime, and carries an IPX6 rating with ISO 8846 ignition protection. It is a practical fit for boats that need stronger freshwater flow without moving to a larger pump platform.

Key features

• 6 GPM (22.7 LPM) open flow rate for freshwater pressure systems with several outlets.
• Integrated sealed pressure switch starts and stops the pump automatically as faucets or fixtures open and close.
• Internal bypass helps smooth flow and reduce rapid switch cycling during normal freshwater use.
• Self-priming up to 7 ft (2.1 m) dry prime, with run-dry capability for added tolerance during startup and tank changes.
• Quick connect ports with two 3/4 in. (19 mm) straight hosebarb fittings for hose connection and service access.
• IPX6 rating, ISO 8846 ignition protection, CE and RCM compliance for marine installation environments.
• Fiber reinforced polypropylene upper housing, cast aluminum lower housing, stainless steel pump head fasteners, EPDM valves and seals, and Santoprene diaphragm in the wetted path.
• 12 in. (305 mm) 14 AWG stripped wire leads for connection to a protected DC circuit.

Variants

The Par-Max HD6 range is offered in four configurations. The pump platform and 6 GPM open-flow rating stay consistent, while the electrical system voltage and pressure switch cut-off change by variant.

The 12 VDC models fit common DC freshwater systems on many boats, while the 24 VDC models match vessels using 24 V service. The 40 PSI versions use a lower pressure switch cut-off, and the 60 PSI versions use a higher cut-off within the same HD6 family.

• P601J-215S-3A: 12 VDC with 40 PSI (2.8 BAR) pressure switch cut-off. This version matches a 12 V freshwater system where the lower HD6 pressure setting is preferred.
• P601J-218S-3A: 12 VDC with 60 PSI (4.1 BAR) pressure switch cut-off. This version keeps the 12 V electrical format and uses the higher HD6 pressure setting.
• P602J-215S-3A: 24 VDC with 40 PSI (2.8 BAR) pressure switch cut-off. This version fits a 24 V freshwater system and uses the lower HD6 pressure setting.
• P602J-218S-3A: 24 VDC with 60 PSI (4.1 BAR) pressure switch cut-off. This version pairs 24 V electrical service with the higher HD6 pressure setting.

Installation and setup

Install the pump on a solid mounting surface in a dry area with ventilation, leaving enough room for the port clips, hoses, and wiring to bend without strain. The baseplate uses rubber feet to help reduce vibration transfer into the mounting surface.

A strainer should be placed before the pump inlet so incoming water is filtered before it reaches the check valves and pressure switch. This is especially important on boats where tank debris, scale, or service residue can move through the freshwater plumbing after maintenance.

Electrical and system integration

The 12 VDC versions operate across a 9 VDC to 13.6 VDC range and use a 25 amp fuse, which is not included. The 40 PSI 12 VDC version draws up to 15 amps at cut-off pressure, while the 60 PSI 12 VDC version draws up to 18 amps at cut-off pressure.

The 24 VDC versions operate across an 18 VDC to 27.2 VDC range and use a 15 amp fuse, which is not included. The 40 PSI 24 VDC version draws up to 7 amps at cut-off pressure, while the 60 PSI 24 VDC version draws up to 8 amps at cut-off pressure.

Materials and marine environment

The wetted-side construction uses fiber reinforced polypropylene, polypropylene, Santoprene, and EPDM components, with stainless steel pump head fasteners. The motor casing combines cast aluminum and coated steel, and the lower housing is cast aluminum.

The IPX6 rating is useful around marine service areas where spray and washdown exposure can happen, but the pump should still be installed where it is protected from standing water and unnecessary bilge moisture.

Use cases on board

This pump is a good match for cruising boats, fishing boats, and larger freshwater layouts that need on-demand pressure at multiple fixtures. A common sizing guide for freshwater delivery is about 1 GPM per outlet, so the 6 GPM rating gives useful capacity for systems serving several outlets.

It can support freshwater supply to galleys, showers, wash stations, and other tank-fed fixtures where steady pressure and automatic operation matter more than a simple transfer pump.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
