About Our Pump Internals
For pump test laboratories, Conestoga USA manufactures a set of vane pump internals which are used as wear specimens in order to judge the anti-wear qualities of the candidate hydraulic fluid or transmission fluid.
Conestoga has spent over 20 years working with ASTM committee members and the labs they represent in order to gain acceptance of the Conestoga pump and to solve the hardware and procedural problems which plagued the original Vickers pump test (D2882, now withdrawn). Conestoga also manufactures a pump housing (B1) which replaces the obsolete Vickers pump housing originally used.
The pump internals are used in:
- ASTM D7043 — Standard Test Method for Indicating Wear Characteristics of Non-Petroleum and Petroleum Hydraulic Fluids in a Constant Volume Vane Pump (previously D2882)
- ISO 20763 — Determination of Anti-Wear Properties of Hydraulic Fluids
- Ford and GM Tests — Similar methods for transmission fluid anti-wear evaluation
The B1 pump housing is accepted by ASTM for use in the D7043 test and has gained acceptance in Europe for use in the ISO method. Some version of the pump test has been in use for over 40 years and Conestoga is uniquely positioned to service its users for the foreseeable future.

Please note that we do manufacture and sell all of the parts listed in the downloadable PDF parts diagram & list, regarding the B1 Punp and PTS-25B Conversion Kit.
The short list viewable here on this page is a quick referance list of the most commonly used items and "wear" items, as these wear items must be replaced in regular intervals as-per the ASTM test method.
Please see the PDF for a more detailed breakdown and parts list for ordering replacement parts for your pump.
PTS-25B Kit
As an adjunct to the B1 pump, Conestoga has fabricated entire pump stands, as well as the PTS-25B Kit which includes the hoses and fittings needed to adapt our B1 pump to a customer's existing Vickers V-104C pump stand.
Whether upgrading an old Vickers pump or assembling a brand new test rig, the PTS-25B Kit has the essentials you need. While the kit contains a standard set of components, each kit may be customized per the customer's needs.
We work directly with the fluid testing laboratories and their technitions when ordering parts.
