Hydra-Cell Pumps Wetted Materials of Construction
Every Hydra-Cell pump is built with manifolds, elastomeric materials and valve assemblies using construction materials specified by the customer. The range of wetted material choices depends on each pump model – for example, models designed to operate at higher pressures are available with metallic pump heads only. Michael Smith Engineers Ltd can help customers in selecting the materials best suited to the process application.
Manifolds
Manifolds for Hydra-Cell pumps are available in a variety of materials to suit your process application. They are easy to replace and interchangeable to accommodate different fluids processed by the same pump. Special manifolds with a 2:1 dosing ratio are also available.
Metallic Pump Heads
Metallic pump heads can handle higher operating pressures. Hastelloy C or Stainless Steel is also selected for corrosion resistance and other properties.
- Brass
- Bronze
- Cast Iron (Nickel plated)
- Hastelloy C
- Duplex Alloy 2205 Stainless Steel
- 304 Stainless Steel
- 316L Stainless Steel
Non-metallic Pump Heads
Non-metallic pump heads are often specified when a corrosive or aggressive fluid is being pumped at lower pressures.
- Polypropylene
- PVDF
Diaphragms and O-rings
Diaphragms and corresponding o-rings are available in several elastomeric materials.
- Aflas diaphragm (used with PTFE o-ring)
- Buna-N
- EPDM (requires EPDM-compatible oil)
- Neoprene
- PTFE
- FKM
