Who we are
Cueroval is a leather pump parts manufacturer based in Aldaia (Valencia, Spain) with 30+ years’ experience. We design and produce leather components for piston & plunger pumps and machinery to drawing or sample, with precise thickness control, flatness and finishing.
What we manufacture
As a leather pump parts manufacturer, our range covers piston cups, leather cup washers, valve leather discs, leather cone cups and leather washers, supplied to drawing or sample. We specialise in leather parts for piston and plunger pumps. Typical thickness range is 2–4 mm (other options on request). We supply standard sizes and custom parts to drawing or based on a physical sample. Short batches are welcome.
Main product families:
- Leather Cup Washers (also called leather cup seals, leather piston cups)
- Leather Valve Discs (valve leathers)
- Leather Cone Cups (conical leather cup washers)
- Leather Washers (flat)
Materials & grades
We mainly work with selected chrome‑tanned leathers because they offer excellent sealing, dimensional stability and durability with oils, water and many process fluids. As a leather pump parts manufacturer we work withhihg quality leather and thicknesses ranging from 2 to 8 mm, but if necessary, we can work on demand. Depending on the application, we can supply different hardness levels and finishes, as well as specific treatments for fluid compatibility and abrasion resistance. Thickness is matched to the drawing and to the pump type so that the seal is progressive and smooth. If you are unsure which leather grade is best, our team will propose the most suitable option for your operating conditions.
Being a leather pump parts manufacturer, we select chrome‑tanned leathers for stability, durability and fluid compatibility in oils, water and many process fluids.
Why leather
Leather offers a unique combination of sealing ability, durability and damping. Properly specified, a leather part can conform to the surface and hold a stable lip while maintaining low friction and good service life. It is also adaptable to custom geometries and small runs, which makes it ideal for maintenance and legacy equipment.
How we work
We follow a clear, traceable process from enquiry to delivery. As a leather pump parts manufacturer first we study the application and choose the right leather grade, geometry, thickness and finishing.
We can prototype or make pre‑series for validation before production.
Production runs are made to drawing with dimensional control and finishing to specification. We handle short lead times and provide documentation when needed.
- Technical review of your drawing, sample and operating conditions.
- Material selection according to fluid, temperature and service.
- Cutting with dimensional control of diameter, thickness and flatness.
- Inspection of every batch (visual & dimensional).
- Finishing according to application (edges, treatment, deburring).
- Documentation when required (COC/COA).
Sectors
Agriculture, pumps and compressors, food and beverage, mining and mechanical equipment, restoration of legacy machinery, and other industrial uses.
Lead times & quality
Your trusted leather pump parts manufacturer for short, reliable lead times and consistent repeat batches with documented specs. Typical prototype lead times 48–72 hours; small runs 5–7 days (subject to workload). We manufacture small and medium series with short, We keep tight tolerances, stable thickness and repeatability between batches.
