Product catalog summary
Introduction
This document outlines the specifications and selection guides for water pressure systems used in leisure vessels, including automatic pressure-controlled pumps, washdown pumps, and accessories like accumulator tanks and check valves.
Specifications
  • Sensor Max™ VSD Constant Pressure Water System Pumps: Feature variable speed drive for 1-5 outlets, maintaining steady flow and constant pressure. They are self-priming up to 10ft, operate quietly, and conserve battery power.
  • Par Max Plus Series: Available in 12 and 24 volt DC models, offering flow rates from 4 to 6 gpm with shut-off pressures up to 70 psi.
  • V-Flo 5.0 Water Pressure Pump: Provides a flow rate of 5.0 gpm with shut-off pressures ranging from 25 to 40 psi.
  • Par-Max Water System Pumps: Models offer flow rates from 1.1 to 7 gpm with varying shut-off pressures.
Procedures and Recommendations
  • Diaphragm pumps are recommended for their self-priming capability and quiet operation.
  • Turn off the pump and open a tap to depressurize the system when not in use.
  • Use accumulator tanks to smooth flow and reduce pump cycling.
  • Inlet water regulators protect plumbing from high municipal water pressures.
Additional Features
  • Washdown pumps are designed for high-pressure cleaning with saltwater-compatible nozzles.
  • Pumpgard™ strainers protect pump valves from debris.
Standards and Compliance
  • Pumps comply with USCG 183.410 and ISO 8846 Marine standards for ignition protection.

Key Features
  • Variable Flow and Constant Pressure: Advanced technology maintains constant water pressure and reduces power consumption.
  • Durability and Efficiency: Features like sealed switches and co-moulded diaphragms enhance longevity and reduce noise.
  • Self-Priming and Dry Running: Many models are self-priming up to 10ft and can run dry without damage.
  • Compliance and Safety: All models comply with ISO 8846 Marine standards for ignition protection.
Recommendations
  • Use low shut-off pressure models with copper water heating tanks.
  • Ensure Sensor Max™ VSD pumps have a battery installed for optimal performance.
Additional Information

05 Water Pressure Systems introdUCtion Pressure Controlled Diaphragm Pumps Pressure controlled diaphragm pumps provide boat owners with a fresh water system that is as easy to use as their domestic water supply – with the versatility to offer full flow or a trickle. The pump is controlled by a switch which senses the pressure drop when a faucet is opened and activates the pump; it turns off when the system pressure builds to a pre-set limit as the faucet is closed. This system allows any type of faucet or shower valve to be fitted, from 3/8” (10mm) bore for minimum water use to ½” (13mm) bore...

083 It probably goes without saying that many Jabsco pumps have more than one possible application. Sometimes it is a simple matter of installing the standard product in the different application. Sometimes Jabsco needs to develop the standard product to meet the particular needs of the different application. Washdown Pumps Washdown pumps are a development of our Water Pressure System pumps. Higher shut-off pressure switches prevent on/off cycling while salt water compatible trigger nozzles let you blast off mud and dirt, and then rinse down. Pumpgard™ Strainers Inlet Strainers are an essential...
