Smart Turner Double Suction Pumps are quality built and of rugged design to provide long, continuous, quiet, trouble free operation in a wide variety of municipal, industrial or other
heavy duty applications. Designed with efficiency and NPSH in mind, all pumps have labyrinth casing wear rings as standard to guarantee low recirculation losses without compromising the premise of
longevity.
Smart Turner Double Suction Pumps are produced in a wide range of sizes, comprising 14 single stage models and 2 two stage models. As many as five models share each of the shaft standards to
ensure a high level of interchangeability and effective parts inventory.
Depending on the application and rating, sizes are available to 14 x 12 x
16, capacities to 8000 USGPM, heads to 750 feet, and speeds to 3600 RPM.
FEATURES
Casing: Axially split, rugged castings with 125 p.s.i. ANSI flat faced flanged connections on the lower casing. Precision machining ensures
alignment of the shaft assembly through the bearing housings and stuffing boxes. Tongue and groove machining locates the wear rings. Easy removal
of the upper casing permits inspection and/or removal of the rotating element without disturbing the connecting piping.
Impeller: An enclosed, fully shrouded, one piece casting. The impeller is
trimmed to meet the exact diameter requirements and is factory balanced. Impeller clearance is factory set and needs no further adjustment. The
impeller is keyed to the shaft and secured axially by threaded sleeve nuts.
Casing Wear Rings: A fully labyrinth design is standard to ensure
minimal recirculation from the discharge to the suction side of the impeller. Tongues and grooves locate the wear rings in the casing.
Shaft:
Machined and ground from high grade alloy, the shaft is designed for maximum strength and rigidity, and minimum deflection. The shaft is threaded for right and left hand sleeve nuts.
Sleeve Nuts: Right and left hand threaded combination shaft sleeve/impeller nuts protect the shaft from wear and corrosion for packed
stuffing boxes. Sleeve nuts are self tightening and eliminate the need for external nuts, keys, and sealing devices. Where mechanical seals are
furnished, right and left hand impeller nuts only are used and the seal mounts direct on a stainless steel shaft.
Bearings:
Grease lubricated ball or roller bearings are selected for long life and continuous service under full load conditions.
Two stage pumps have an intermediate bearing consisting of a bearing
shell and distance sleeve which separates the impellers. This bearing also serves as a restriction bushing for leakage between the stages, and is lubricated by the liquid being pumped.
Bearing brackets with integral drip reservoirs for stuffing box leakage, house and protect the bearings. Replaceable cartridge housings are
standard on 6 and 8 inch pumps and are located in the bearing brackets with tongues and grooves.
Stuffing Boxes: Designed for easy access and to accommodate a wide
range of packings, the stuffing boxes are packed as standard and have neck rings and lantern rings with flush lines from the casing. Lantern rings
are not required nor fitted for services where good suction pressure is present. Lantern rings for connection of external flush lines are available for
fluids containing abrasives. Single mechanical seals are available.
Glands: Solid, one piece glands are standard for packed stuffing boxes
and mechanical seals. The glands can be provided in a variety of arrangements to suit the application.
lnterchangeability: Pumps on the same frame have fully interchangeable
shafts, sleeves, bearings, packing, seals,  glands and hardware resulting in
an efficient parts inventory at both the factory and customer.
Tests: All pumps are hydrostatically tested to 50 p.s.i. above the maximum casing design pressure.
