High-Performance Fluid Transfer & Environmental Alert Systems

Preventing hydrocarbon discharge into storm drains and municipal watercourses requires a combination of real-time detection alarms and heavy-duty recovery equipment. Cowens manufactures the CB2800 Oil-on-Water Monitor, heavy-duty Peristaltic Transfer Pumps, and Sockit Drain Absorber Inserts to ensure full compliance across industrial sumps, interceptors, and site drainage networks.

Whether automating early pollution alerts in site sumps or decanting thick hydrocarbon sludges away from oil skimmers, our specialized accessories deliver robust, low-maintenance site protection.

1. CB2800 Oil on Water Monitor & Alarm

The CB2800 Oil on Water Monitor is an automated optical/conductive sensing system engineered to detect thin oil sheens floating on water surfaces. Designed for permanent installation in drainage sumps, interceptor chambers, and discharge outlets, it continuously monitors water quality and activates local alarms or remote telemetry before oil escapes off-site.

CB2800 Monitor Features:

• Continuous Surface Sensing: High-sensitivity detection responds instantly to floating hydrocarbons and fuel sheens.
• Fail-Safe Alert Outputs: Triggers visual beacons, audible sounders, automated shut-off valves, or BMS/GSM telemetry.
• Rugged Weatherproof Design: IP-rated sensor assembly built to withstand harsh industrial sumps and outdoor watercourses.

2. Heavy-Duty Peristaltic Transfer Pumps

Our Peristaltic Pumps provide powerful positive displacement suction for decanting recovered oils, heavy crudes, and emulsified sludges from skimmers or holding sumps. Because pumped liquid stays entirely inside the reinforced internal tube, pump wear is minimized, and cross-contamination is completely prevented.

Peristaltic Pump Advantages:

• Self-Priming High Vacuum: Dry-running capabilities with suction lifts up to 9 metres.
• Shear-Sensitive Pumping: Prevents further emulsification of oil and water mixtures during transfer.
• Reversible Flow: Reverses suction easily to clear line blockages or drain supply hoses.

3. Sockit Drain Oil Absorber & Filter Inserts

The Sockit System is a modular drain insert designed to fit into roadside gullies and site sumps. It actively absorbs floating hydrocarbons while allowing clean rainwater to pass through unrestricted, providing a vital first line of defense against surface runoff pollution.
