12V Caravan Water Pump – 11.3 L/min, 55 PSI, 4009 Style
Description
Compact 12V pressure water pump designed for caravans, RVs, campers and other mobile water systems. The popular 4009-style diaphragm pump delivers up to 11.3 L/min at 55 PSI and features an integrated Honeywell pressure switch for automatic operation when taps or showers are opened.
12V Caravan Water Pump – 11.3 L/min, 55 PSI
The SP12V4009 is a compact diaphragm pressure pump suited to caravan, RV, camper and mobile water installations. Its compact dimensions allow installation in restricted spaces, while smooth and relatively quiet operation makes it well suited to onboard water systems.
The pump automatically starts and stops according to water demand using an integrated Honeywell pressure switch. An internal bypass valve helps reduce rapid pressure-switch cycling when operating at lower flow rates.

Automatic Pressure-Controlled Operation
The integrated pressure switch allows the pump to operate automatically with the water system. Opening a tap or shower causes system pressure to fall and the pump starts automatically. Once the outlet is closed and system pressure recovers, the pump switches off.
An internal bypass valve works with the pressure-control system to improve operation at lower flow rates and reduce rapid on/off cycling.
Caravan, RV & Camping Applications
The compact size and automatic operation make this pump suitable for a range of clean-water applications including:
- Caravans and camper trailers
- Motorhomes and RVs
- Camping water systems
- Onboard taps and sinks
- Showers
- General mobile clean-water transfer
Compact & Quiet Design
The pump is designed for installation where space is limited and typically operates at approximately 50–55 dB. This makes it well suited to caravan and RV installations where noise and available mounting space are important considerations.
4009-Style Replacement Pump
The SP12V4009 uses the common 4009-style pump configuration and is designed as a replacement option for many installations using Shurflo 2088 and Shurflo 4009 pumps.
Always compare the dimensions, mounting arrangement, electrical requirements and plumbing connections with the existing pump before installation.
