03
Enjoy Water on Demand Without the Disruption
The pump system combines a quality motor, sound-dampening pump housing, solid metal mounting base and four anti-vibration rubber feet to help reduce operational noise and resonance.
Quality Pump Motor
Engineered to provide dependable pressure while helping maintain smoother, quieter operation.
Sound-Dampening Housing
The pump housing helps absorb operating sound before it transfers into the surrounding installation area.
Anti-Vibration Rubber Feet
Four soft mounting feet help isolate vibration from the floor, wall, cabinet or vehicle body.
SMOOTH AND STABLE WATER FLOW
Three Components Working as One System
The 5-chamber pump, accumulator tank and vibration-isolating base work together to create stronger pressure, smoother delivery and more comfortable water use.
Strong, Consistent Pressure
The five-chamber diaphragm configuration provides up to 5.0 GPM of flow for dependable water delivery across compatible fixtures.
- Up to 5.0 GPM water flow
- Maximum pressure of 70 PSI
- Suitable for multiple fresh-water applications
Smoother Water Delivery
The integrated accumulator tank stores a small volume of pressurized water and releases it as demand changes.
- Helps stabilize water pressure
- Reduces noticeable flow pulsation
- Supports more comfortable showering
Reduced Noise and Vibration
A rigid metal base and four rubber feet provide a stable mounting platform while helping isolate motor vibration.
- Four anti-vibration mounting feet
- Rigid metal support platform
- Helps reduce resonance and movement
BUILT FOR DEPENDABLE PERFORMANCE
Upgraded Where It Matters Most
From the five-chamber pump head to the metal fittings and reinforced mounting platform, the system is built to handle regular mobile and off-grid water use.
5-Chamber Pump
The five-chamber design supports strong flow and consistent pressure, providing an upgrade over conventional four-chamber pump designs.
Durable Metal Fittings
Reinforced connection components provide a secure interface between the pump and integrated accumulator tank.
Metal Mounting Base
The complete pressure system is installed on a rigid platform for easier positioning and improved structural stability.
Motor Overload Protection
Integrated protection helps safeguard the motor when abnormal operating conditions place excessive demand on the system.

TANK SMOOTHER FLOW
BUILT-IN PRESSURE BUFFER
Reduce Rapid Pump Cycling
Without an accumulator, small changes in water demand can cause a pump to switch on and off repeatedly. The integrated 1.0 L tank absorbs pressure changes and supplies small amounts of stored water before the pump needs to restart.

Fewer Start-Stop Cycles
Helps reduce unnecessary pump activation during low-flow or intermittent water use.
-
✓
Reduced Pressure Pulsation
Buffers pressure changes to help maintain smoother flow from showers and faucets.

Spend Less Time Building the System
The pump, accumulator tank and mounting base arrive together as a compact pressure set. This reduces the number of separate components that need to be positioned and connected during installation.
Choose a Suitable Location
Select a dry, ventilated and accessible area with adequate space for plumbing, wiring and future maintenance.
Secure the Metal Base
Mount the system to a solid surface without fully compressing or bypassing the vibration-isolating rubber feet.
Connect the Plumbing
Follow the marked flow direction and use compatible hoses, fittings, clamps and sealants.
Complete the 12V Wiring
Connect the pump using correctly sized wiring, overcurrent protection and a suitable switching method.
