Jabsco 23870 Series Diesel Refuelling Pump, 35 L/min, IP55, ISO8846

Overview

The Jabsco 23870 Series is a 35 L/min diesel refuelling pump range for controlled fuel transfer from drums, day tanks, and service containers into small diesel tanks. It is a self-priming sliding vane pump family with 12 V DC and 24 V DC versions, port options for either 1/2 in BSP parallel internal connections or 19 mm hose ports, and a maximum head of 6 m.

This range suits boat owners, service crews, and marine operators who need a compact DC pump for diesel refuelling away from a fixed fuel dock. The motor is IP55 protected, vibration tested, and ISO 8846 marine ignition protected, which matters when the pump is installed or used around equipment that sees movement, spray, and fuel vapour risk.

The pump is intended for diesel transfer and related fuel service duties, not for gasoline, solvents, thinners, or other highly flammable liquids. Match the voltage to the vessel or service battery system and choose the port style that fits the planned hose or threaded plumbing layout.

Key features

• 35 L/min flow rate helps move diesel quickly when topping off auxiliary tanks, generators, or small diesel-powered equipment.
• Available in 12 V DC and 24 V DC versions for matching common onboard electrical systems.
• Port choices cover 1/2 in BSP parallel internal ports or 19 mm hose ports, giving flexibility for fixed plumbing or hose-based transfer setups.
• Self-priming pump design supports practical use with drums and remote containers where the fuel source sits below the pump.
• Maximum head of 6 m gives useful lift and delivery range for service carts, deck-level refuelling, and equipment-side fuel transfer.
• IP55 protected motor helps guard against dust and water spray in service areas, lockers, and dockside work spaces.
• ISO 8846 marine ignition protection supports use in marine fuel-transfer environments when installed and operated correctly.
• Switch and fuse are included across the listed configurations, with one 24 V hose-port version also including a check valve and suction strainer.

Variants

The range is offered in multiple configurations so the pump can be matched to the vessel voltage and the connection style used in the fuel transfer setup.

The main differences are voltage, port type, and included accessories. The 1/2 in BSP versions suit threaded plumbing layouts, while the 19 mm hose-port versions suit hose-based diesel transfer arrangements.

• 23870-2200: 1/2 in BSP parallel internal ports, 12 V DC, with switch and fuse. This version fits 12 V systems where a threaded-port pump is preferred for a more fixed fuel transfer installation.
• 23870-2300: 1/2 in BSP parallel internal ports, 24 V DC, with switch and fuse. This version suits 24 V electrical systems with threaded fuel-line connections.
• 23870-1200: 19 mm (3/4 in) O/D hose ports, 12 V DC, with switch and fuse. This version works well for 12 V hose-based transfer setups where quick connection to diesel hose is the priority.
• 23870-1300: 19 mm (3/4 in) O/D hose ports, 24 V DC, with switch and fuse. This version pairs the hose-port layout with 24 V onboard or service power.
• 23870-1600: 19 mm (3/4 in) O/D hose ports, 24 V DC, with switch, fuse, check valve, and suction strainer. The added check valve and suction strainer give this configuration extra support for controlled pickup-side fuel handling.

Installation and setup

Install the pump where it can be reached for switching, inspection, and hose management, while keeping fuel lines as short and direct as the vessel layout allows. The selected model should match the available DC supply, and the circuit should use the included fuse as part of a properly protected marine electrical installation.

For hose-port versions, use fuel hose that matches the 19 mm connection and is suitable for diesel service. For BSP versions, use compatible threaded fittings and sealing methods appropriate for diesel fuel systems. Keep suction-side restrictions low so the pump can prime cleanly and maintain transfer flow.

Use cases on board

This pump range is a practical match for diesel refuelling tasks on cruising boats, workboats, service tenders, and dockside maintenance setups where fuel is transferred from a drum or portable container. It can also support generator refuelling and small auxiliary fuel-transfer jobs when the liquid, voltage, and plumbing are matched correctly.

Because it is a diesel transfer pump, it should be kept separate from potable water, bilge, and general fluid-transfer duties. Clearly marking the installation and hoses helps prevent cross-use and keeps fuel handling safer and more predictable.
