In our flame spray metallizing process, a proprietary
nickel/stainless steel composite, that is more resistant to abrasion
and chemical attack than original uncoated OEM components, is
applied to critical wear areas. Service life of sprayed components
is often better than that of original components.
Areas worn by contact with shaft seals and plate bushings are
ground, filled with thermal sprayed nickel/stainless steel composite
and then ground to OEM dimensional and surface finish
specifications. Edges and vane slots are deburred and then the
entire assembly is polished.
Option #1: Worn piston slide bore IDs are enlarged and fitted
with cast iron bushings, which are then bored to OEM dimensional
Option #2: Piston slide bore ID is enlarged and the component is
mated with an oversized eccentric. (See illustration below)
Option #1: Areas worn by contact with piston slides are ground, filled thermal
sprayed nickel/stainless steel composite and then ground to OEM
dimensional and surface finish specifications. Edges are deburred
and then the entire assembly is polished.
Option #2: Eccentric lands are oversized to meet
clearance specifications with a mated oversized piston slide bore.
Stokes pump blocks are bored to standard or custom oversized
dimensions. As part of the service, matching oversized hinge bars
and a spacer (if required) are supplied.
Up to three options are available for reworking plates, depending
upon the magnitude of wear (See

then bored to exacting dimensions to provide proper shaft
alignment. Carbon bushings are used for certain pump models

Remove all items such as pins, keys and nozzles from plates,
shafts and rotors. Gasflo is not responsible for returning such items.
Parts must be cleaned, degreased, and tagged with a part number or
description. Please indicate the type of chemicals that passed through the
pump. Gasflo must be notified if incoming components were exposed to
hazardous chemicals. Contaminated components will be returned at
package components securely to prevent shipping damage. DO NOT package
components in Styrofoam “popcorn”. Components will be inspected upon
receipt to make sure they can be reworked to OEM specifications. If there
is any question, we will contact you.
