NASH CL9002

REBUILT NASH CL9002 VACUUM PUMP

Body: We will repair weld all washed areas, pre-machine to accept a stainless steel (SS) liner,

using (SS) material. The sweep area will be 1⁄4” thickness to the side. The center shroud will be

constructed of 1⁄2” (SS) material. The outer body shrouds on drive end (DE) and idle end (IE)

will be 1⁄2” (SS) to the side. The sweep area will be held fast using plug welds to (SS) installed

from the cast iron to the (SS) liner for sealing purposes (approximately 20 plug welds). We

offer this special process as a special two step welding procedure between cast iron and (SS) at

the gasket areas. The (SS) liner acts as a body within a body with no exposed cast iron. We fill

the voided space between the liner with fiberglass resin to insure there is an absence of resonance

created. All plugs on the body are drilled oversized and (SS) bushings installed, tapped, and

capped off with (SS) plugs.

Cones: We will machine a cut of approximately .250 around the sides of both cones. We will

roll a stainless-steel 1⁄4” thick clad around the cones and machine cut to print specifications. We

will anchor the (SS) cladding to the cones with a series of plug welds using stainless steel

rod\wire. The openings around the inlets and discharge ports will be welded and ground smooth.

The cladding will be welded around the end tips, and the inner most area of the cone tapers. The

installed cladding will be machined to finished print specifications.

Heads: We will machine a cut around the circumference of the head where the rabbets fit and

gasket surfaces connect. A machined cut will be removed from the face of the head adjacent to the

rabbet fit area. A machine cut will be made to accommodate the installation of a 3/8” precise

circular shaped stainless steel wear face plate. The (SS) wear plate will be anchored\affixed with

plug welds around the circumference of the rabbets fit area. The installed wear plates will be

machined to finished print specifications.

Rotor: A machined cut from the three (3) shrouds will be made, and fabricated stainless steel

wear rings will be installed onto the rotor shrouds. The outer edges on the I.D. of the stainless

rings will be chamfered. A weld at the outer side of the ring and face of the rotor will be made to

bond the ring to the surface. A weld will be made to the inner face of the rotor shroud, filling the

chamfered ring with nickel rod\wire. The installed ring will be machined across the outer side to

finished print specifications. Any worn areas, on the rotor buckets, shrouds etc. will be filled

with nickel rod\wire. A machine cut will be taken in the taper-bore area to allow the installation

of stainless-steel cladded cones.

The following new shop supplies will be installed:

Bearings Clipper Seals

Gaskets Packing

O-rings Misc. Small Parts

Warranty: The pump, if repaired as stated above, will be guaranteed 95% new pump capacity,

and will carry a two (2) year parts, and workmanship, warranty from the date of installation.
