ETP - DEIGN FEATURES                                                       1 Large Priming Chamber : Injection moulded corrosion resistant polypropylene self-priming chamber retains liquid for priming and enables pump to lift up to 3 mts.   8 Ball Bearings: Inboard bearing is pressed on shaft and free to float axially in frame - carries radial load only. Outboard double row ball bearing is shouldered and locked on shaft with lock-nut and washer, and in bearing housing to carry radial and any unbalanced thrust load. All bearing fits are precision bored.           2 Check Valve : Prevents back - flow siphoning and allows for faster restart.   9 Shaft : Designed for maximum 0.05 mm deflection at mechanical seal. Available in EN / Stainless Steel.           3 Impeller : Non-clog, semi-open ‘S’ type impeller suitable for handling slurry, sludge and solids up to 10mm..   10 Sleeve : Shaft Sleeve of different material depending on the compatibility of the liquid to be handled.           4. Volute: Self-priming and self cleaning double volute primes, during pumping keeps pump free from settled solids. Made from glass filled polypropylene for longer life.   11 Mechanical Seal / Gland Packing : Pumps are fitted with either mechanical seal or gland packing depending on the service conditions.           5. Wear Plate: Moulded glass filled polypropylene, minimises effects of abrasion   12 Clamping Bands : Powder coated steel clamps holds the housing halves securely. Releases quickly for easy cleaning and maintenance of pump internals.           6. Back Plate: Sturdy ribbed backplate suitable for Mechanical Seal or Gland Packing.   13 Suction Strainer: Injection moulded corrosion resistant polypropylene Strainer to protect from foreign ingression.           7. Bearing Frame: Heavy Cast Iron construction, precision machined for no shaft deflection of more than 0.05mm contains large oil reservoir.
