The EFFLU GRINDER: Consists of a Polyethylene tank complete with a discharge non return valve and couplings for all invert, discharge & vent connections including reflux (non return valve). The entire unit is damp and flood-proof and thus ideally suited to placing in unventilated areas or basements subject to accidental flooding. It incorporates a Control Panel with overload relay, alarm device, high level alarm and volt free contacts for remote alarm. Install Control Panel in dry area. TECHNICAL DATA DESCRIPTION Pump: Single stage vertical centrifugal pump, with open 3-blade impeller, horizontal 1½" flanged discharge branch, and adjustable Multicut cutting system. Shaft/Bearings: Combined pump/motor shaft, protected against contact with pumped liquid, and rotating in grease-packed ball bearings. Shaft seal: Oil-filled seal chamber between pump and stator casing with wear-resistant silicone carbide primary seal with dry running properties and duplex lip seal as secondary seal. Motor: Submersible motor with "dry" type stator windings class F insulation, watertight cast iron enclosure (IP 68) supplied with multicore flexible cable with polychloroprene outer sheath. The pumps are also available with explosion-proof motors (EEx dll BT4) in accordance with German specification V.D.E. 0171. Materials: Cast iron pump and motor casings and impeller, corrosion protected shaft (no contact with pumped liquid) stainless steel hardened (HRC 57) cutting system. Maintenance is extremely simple: the tank has a top mounted inspection/cleaning aperture and, if necessary, the pumping unit can be removed/replaced in minutes and without disturbing the tank assembly.
