Frequently Asked Questions
How much longer do carbide plungers last vs steel?
Typically 3–5 times longer in oil and gas, chemical pump and industrial equipment service.
Which surface finishes are available?
Ground and polished finishes for sealing surfaces; finish specification is confirmed in the quotation.
Can you make stepped diameters and threads?
Yes — stepped profiles, threads and grooves are produced to drawing.
Do you support custom sizes for plungers and cylinders?
Yes. We produce to your drawings (PDF, DWG or STEP). Send specifications and our engineers will confirm feasibility and provide a quote within 24 hours.
What is the typical lead time?
Standard items are usually shipped in 7–15 days. Custom parts depend on complexity and are confirmed with the quotation.
