Marine and RV water accessory designed to steady pressure and reduce pump cycling, the Cocoarm Accumulator Tank helps maintain consistent flow for onboard taps and sprayers. Quieter, more reliable water delivery eases daily chores and reduces wear on pumps for boat owners and caravanners. Is capacity and pressure rating right for your system?
⚡ At a Glance
- • Pressure Performance: Maximum inlet pressure 125psi with a 0.75L charge chamber to steady output
- • Best for: Owners of yachts, motorhomes and caravans needing steadier onboard water
- • Not ideal for: Systems requiring large-volume buffering or integrated electronic pressure control
Compact accumulator for pressurised water systems in marine and vehicle use. Reduces pump cycling and smooths flow, especially at low rates.
Fewer pump starts – Thanks to 0.75L pressure buffer
A 0.75-litre chamber stores pressurised water up to the rated inlet pressure, releasing it between pump cycles. The stored volume reduces the frequency of automatic refills and safety valve activations.
Reduced pump starts lengthen pump life and lower energy use, particularly useful on small onboard water systems.
Smoother flow at low rates – With efficient pressure control
Accumulator action acts as a hydraulic buffer that evens out short-term pressure fluctuations, maintaining steadier output during low-flow tasks. The mechanism prevents abrupt cycling by compensating for brief demand changes.
Steadier water from taps and sprayers makes tasks such as washing up or filling containers less fiddly.
Quiet, low-energy operation – With excellent sealing and compact design
Low power consumption and reduced noise result from fewer pump cycles and effective sealing that prevents unnecessary top-ups. The compact, waterproof construction supports simple installation in confined spaces.
Quieter cabins and less maintenance, a practical choice where space and noise are concerns on boats and caravans.
