Super Flow Demand/Delivery Pumps - 20 litre/min
550 Series

The 5 chamber 550 Series delivery pumps provide higher flow rates than their smaller, 3 chamber 5800/7800 counterparts. Similarly, the 550 Series can be used to either a) draw water from a holding tank and pressurize it, or b) boost pressure from a low-pressure source. Although designed to operate intermittently, many 550 versions can run continuously for several hours at a time. These pumps can be operated either in demand mode (pressure switch controlled) or in delivery mode (controlled by external power switching device). If needed, an integral bypass can be used to limit pressure.

Technical Specifications
POWER: Depending on flow and pressure, power demand varies from 50W to 200W. Motors are available in various configurations ranging from 12 VDC to 230 VAC. Transformers or DC power supplies are optional and, if applicable, must be ordered separately. Standard terminations are 12 long, 16 AWG lead wires with a stripped end. Connectors or cords with plugs are optional.

MOUNTING: These pumps may be mounted in any position. A steel mounting base with four hollow rubber grommets is included at no extra cost.

FITTINGS: Standard pump heads have a 3⁄4” port opening that accepts quick-connect beverage style O-ringed barb fittings, for use with 5/8” (16mm) ID tubing. These pumps are also available with a 1⁄2” NPT female port. Please contact us for recommendations to optimise your system.
