Specifications

Casing
Top Centre line Discharge, Self-venting Casting, arranged for back pull-out fully confined PTFE gasket. Foot support under casting for maximum resistance to misalignment and distortion from pipe loads, working pressure upto 2550 KPa. Minimum 3 mm corrosion allowance, for maximum corrosion-erosion resistance. Casting is supplied without tapped openings, but drain plug openings are provided only when specified

Base Plate
M.S fabricated drip rim type. Only nine sizes of base plates accommodate all pump sizes and all applicable IS or IEC frame size motors

Frame Adapter
Heavy cast iron construction and precision machined to keep bearing frame & casing in perfect alignment. Furnished with lifting eye-bolt for ease in maintenance. Open construction gives easy access to the stuffing box area. Either frame adapter or drip tray may be piped drain Jack Bolt tapping are standard for easy removal of casing for maintenance.

Haft Sleeve
Renewable shaft sleeve is positive drive, key way type with one end free to expand with temperature variations. PTFE 'O'- ring prevents leakage under sleeve. Sleeve permits application of inside balanced mechanical seals where required. Sleeves is hard chrome Planted & Ground for maximum seal & Ground life.

Bearing Frame
Sturdy cast iron construction provides rigid bearing alignment and shaft support. Contains large oil reservoir with water jacket. Oil level is maintained by constant level oiler with visible oil supply. Oil seals on each end and oil breather fully protects oil from contamination while allowing for expansion or contraction of air caused by ambient temperature change. TO handle liquids above 175 C, cast integral cooling chamber is designed for 600 Kpa working pressure or 900 KPa test pressure

Impeller
Fully open, has partial shrouds for maximum vane support without high thrust inherent in full shroud designs. Matched to casing for high efficiency and low NPSH. Impeller is tightened on shaft with nut and threads are sealed by a PTFE 'O' Ring. Impeller nut assures non opening impeller with wrong rotation of motor. Large smoothly contoured flow passages combine best slurry and solid handling ability. All impellers are statically and dynamically balanced.

Bearings
Inboard bearing is pressed on shaft and is free to float axially in frame - carries radial load only. Outboard bearing is shouldered and locked on shaft with locknut and star washer and in bearing housing to carry radial and any unbalanced thrust load. All bearing fits are precision board. Inboard bearing is single row, deep groove. Outboard bearing is double row, deep groove angular contact. Both bearings are sized for two year minimum life.

Coupling
A spacer type coupling is provided to take full advantage of the back pull-out feature. Standard RATHI (love joy) make RRs-type coupling is supplied unless otherwise specified.

Shaft
A single piece shaft is designed for 0.05mm maximum deflection at stuffing box face. All critical surfaces ground to less than 0.8micron.

Stuffing box cover
Encloses back of casting and contains stuffing box chamber. Cover is fastened to frame or adapter so that a spare back pull-out assembly can be stocked completely assembled. Cover can be supplied with jacket for cooling stuffing box chamber in high temperature services. Jacket can also be used for heating viscous or high freezing point liquids. Packed box has 4 ring of Packing and a lantern ring. Quench gland with taps and an auxiliary ring of packing is standard. Gland is split for easy removal. Tapped openings to lantern ring permit "In & out" sealing, external flushing or lubrication as required. Stuffing box is completely machined for mechanical seal installation, either originally or as a field conversation. Inside, out-side, unbalanced, balanced single, double or tandem seals with any required gland, throat bushing,throttle bushing and flushing lines furnished to meet individual sealing problems. Gland completely confines stationary mating ring gasket
