Precision CNC Machining for Fluid Handling

Plastic Parts Machined for Pumps and Valves

PlasticCNCPro manufactures precision CNC-machined plastic components for pumps, valves, and fluid-handling systems. From chemically inert seats and seals to wear-resistant bushings and impellers, we turn drawings and samples into reliable parts for prototyping, low-volume production, and repeat manufacturing.

What We Machine for Pumps and Valves

Comprehensive plastic component manufacturing for fluid-handling systems, from critical sealing surfaces to structural housings.

Valve Components

Seats, poppets, cages, disks, stem guides, packing supports, lantern rings, and precision sealing surfaces.

Seals & Rings

Seal rings, back-up rings, thrust washers, guide rings, O-ring glands, and custom sealing profiles.

Bushings & Wear Parts

Bushings, bearings, wear rings, wear strips, sleeves, and anti-extrusion components for rotating and reciprocating service.

Rotors & Impellers

Impellers, rotors, vanes, spacers, couplings, and flow-directing components for pump assemblies.

Housings & Manifolds

Pump housings, covers, end plates, manifolds, distributors, and custom fluid routing blocks.

Specialty & Custom

Nozzles, orifices, restrictors, flow components, isolation parts, jigs, and reverse-engineered legacy parts.

Materials for Pump and Valve Applications

We machine a wide range of engineering plastics and high-performance polymers to suit chemical, thermal, and mechanical demands.

PT

PTFE (Virgin & Filled)

Chemically inert, lowest friction. Glass/carbon/bronze-filled for seats and seals.

PK

PEEK (Virgin, Glass/Carbon-Filled)

High strength and temperature, excellent chemical resistance for bushings, seats, and wear parts.

PV

PVDF

High purity and chemical resistance for semiconductor, chemical dosing, and chlorinated water service.

PO

POM/Acetal (Delrin)

Excellent dimensional stability, low moisture absorption for gears, impellers, and guides.

PS

PPS & PPS GF

High heat and chemical resistance for structural valve components.
