DE LAVAL (T>AO) PUMP
SERIES A3D
ROTOR SIZE UP TO 187
PLAINTIFF'S EXHIBIT
The De Laval IMO pump is a constant-displacement, rotary, screwtype pump. Fluid is propelled axially in a constant, uniform flow through the action of just three moving parts--a power rotor and two idler rotors. The smooth intermeshing of these rotors propels the fluid axially without churning, pocketing or pulsation. There are no timing gears, cams, valves, sliding vanes, or reciprocating parts to wear or become noisy. Quiet, compact IMO pumps are excellent for direct-connected, high-speed operation; they mount in any position without factory modification.
IMO-151
Inlet can be ro tated to suit in stallation arrange ment.
Fluid at pump discharge pressure, bled through oil balance tubes to the inlet end of the idler rotors, acts on pistons which keep the idlers in constant hydraulic bal ance.
IMO Pumps can accommo date either conventional packing or mechanical seals.
Internal parts are designed as a package so that units can be built into your ma chines.

STANDARD SPECIFICATIONS
STANDARD SPECIFICATIONS
HEAVY-DUTY CASING Casing is high-tensile, close-grained Meehanite; every case is hydrostatically tested.
INLET AND OUTLET OPENINGS Standard pipe tap.
ADJUSTABLE INLET OPENING May be rotated to suit customer's piping arrange ment.
ACCURATELY MANUFACTURED ROTOR HOUSINGS Rotor housing or sleeve is Meehanite. Special fixtures used during manufacture insure concen tricity of rotor bores with respect to the casing and also insure interchangeability.
ROTORS Power rotor is heat-treated chromium-molybdenum steel, nitrided and ground during manufacture.
Idler rotors are Meehanite, induction hardened and ground.
COMPLETE HYDRAULIC BALANCE Fluid at pump discharge pressure, bled through oil balance tubes to the inlet end of the idler rotors, acts on pistons which keep the idlers in constant hydraulic balance.
MOUNTING VERSATILITY IMO Pumps require no special modifications for mounting in any position--horizontally, vertically or inclined.
BEDPLATE IMO Pump bedplates are constructed of fabricated or channel steel.
COUPLING Selections are conservatively made in accordance with coupling manufacturer's published horse power ratings.
TWO SEALING METHODS AVAILABLE MODEL A3DB Model A3DB is fitted with a mechanical seal and a ball bearing for overhung load.
MECHANICAL SEAL A bellows-type seal has been adopted after exten sive testing to prove its serviceability. The bellows is Buna-N synthetic rubber; the carbon- and castiron mating faces are lapped to insure perfect sealing and long, trouble-free service.
BALL BEARING A cartridge-type, pre-packed, dust-resistant ball bearing maintains perfect seal alignment under any normal overhung load from V-belt or chain drive.
MODEL A3DF Model A3DF is equipped with a conventional packing box.
SHAFT PACKING Conventional packing consists of alternate rings of die-formed hard and soft packing. Soft rings are square plaited asbestos; hard rings are square flexible metallic.
PACKING-BOX PRESSURE CONTROL The mechanical seal or shaft packing is subject to low fluid pressure through a pressure break down labyrinth from pump discharge. The fluid is relieved from the seal chamber through an internal relief line connected to the suction chamber of the unit. The fluid is relieved from the packing chamber through an external line containing a valve which sets the packing chamber pressure to lubricate the packing and prevent air from being drawn in around the shaft on suction lift applications.
