The Nex Flow Drum Angel is a versatile “reversible” drum pump that uses only compressed air to operate. When tested against others it is the most efficient on the market using 19 SCFM at 80 PSIG to empty or fill a drum in less than two minutes. The reversible feature allows you to transfer fluids in and out of a drum easily minimizing maintenance time.
These types of systems have been around for many years – some being made of aluminum, some steel and with various accessories. One of the “tricks” some competitors use is to offer a basic system at about the same price as Nex Flow and then offer extras such as a proper squeegee for floor cleanup costing the customer more money that initially thought.
Nex Flow offers a complete system with all accessories to address most applications from coolant transfer, gear box emptying and filling, to floor clean up and more. The Nex Flow Drum Angel is made of stainless steel and is precision machined to give top performance.
The units should always be used only on sealed metal drums of minimum 1 mm (16 gauge) thickness. Plastic drums and weaker drums will bubble under pressure or collapse under vacuum. The units have built in safety features: a pressure relief if the drum reaches a critical pressure and a float system which turns off the air flow to the unit to prevent overfilling.
One caution on such pneumatic systems is to avoid using them with highly flammable liquids, but is completely safe for water, coolant, detergents and gear oils. Used mainly for liquids close to the viscosity of water, they have also been user to transfer more viscous materials although they will operate slower.
The main advantages are near zero maintenance (with the occasional cleaning of the float area if transferring oils or sticky material), and with minimal moving parts except for the knob to convert from filling to emptying and back. They are long lasting with stainless steel construction to be able to handle a wide range of materials.
