Application Uses

AFL sludge pumping systems are designed to remove settled solids from the bottom of the company's separators, clarifiers, and similar pollution control equipment. Two types of systems are available: timer controlled and manually controlled. The timed system also incorporates a manual override.

A sludge system consists of a diaphragm pump, an enclosed control panel, wiring, and plumbing to the point of sludge origination.

The pump used in these sludge handling systems is typically a self-priming diaphragm type. It pumps almost anything that passes through the suction line: sludge, mud, sand, and machining chips.

All wiring in an AFL sludge pumping system conforms to applicable provisions of the most recent issue of the National Electrical Code (NEC). Standard pilot control voltage is 120V AC, 60 Hz, and all indicating lamps, pushbuttons and selector switches are mounted on the front of the enclosure. External line voltage wiring is enclosed in conduit, and control panels are mounted in NEMA type enclosures appropriate to the environment: weatherproof or explosion-proof. In addition to the pilot devices, the controls include a magnetic starter and can include two timers.

The starter prevents electrical damage to the pump by providing low-voltage release and overload protection. The time devices include a seven-day timing switch and a cycle timer.

The pre-engineered system is factory built and installed, ready to operate. It offers dependable, programmable removal of settled solids.
