Tapered
Roller Bearings
Oil
lubrication; minimum B-10 life of 100,000 hours. Optional grease lubrication
Stuffing Box
Suitable for either packing or a variety of mechanical seals. Machined
register fits assure concentricity with shaft. Stuffing box is provided
with two 3/8" NPT flush taps.Replaceable Rear Liner
Extra thick wear surface manufactured of high-chrome cast iron (28HC650)
for extended wear life. Drilled and tapped holes provide secure fastening
to bearing frame.
Extra Heavy Reversible Casing
Ample wall thickness for longer life. Casing can be reversed for rotation
in either direction. High-chrome cast iron (28HC650) construction.
Suction
Cover
Removable suction cover allows easy access to pump internals for maintenance;
provides extra heavy replaceable wear surface for longer life in abrasive
service. High-chrome cast iron (28HC650) construction.
Impeller
Fully recessed cup-type design for maximum solids handling. 650 BHN
high-chrome cast iron (28HC650) construction for superior wear resistance.
State-of-the-art design provides higher efficiencies than other recessed
impeller pumps. Back pump-out vanes reduce stuffing box pressure and minimize
solids entry into the sealing area.
Positive Drive
Machined fit, straight bore, key drive provides positive torque transmission
that is unavailable with other hard metal pump designs. No trial fits
or re-babbitting is required.
Positive Liquid
Sealing at Impeller
Fully confined O-ring between impeller and sleeve protects shaft from
pumpage.
Machined Fits
Fully machined wet end registered fits with confined O-rings provide
positive alignment and ease of maintenance throughout the entire pump.
Close tolerance design minimizes wear.
Shaft Sleeve
Pump shaft is protected by a 420 stainless steel hook-type shaft sleeve
hardened to 450 BHN.
Cast Integrated
Supports
Cast support legs increase strength, minimize vibration and offer
simple mounting.
Heavy Duty Shaft
Rugged high-carbon AISI 1045 HR steel designed for toughest services.
Standard Flange
Connections
Machined flat-faced & drilled flange connections for reliability
Sight Glass &
Vent
Oil lubricated units feature sight glass for simple inspection.
Optional Casing
Vent & Drain Taps
Optional vent and drain tapped openings enhance serviceability.
Optional Gauge
Taps
Machinability of 28HC650 allows the option of 1/2" suction and discharge
gauge taps. |
