| Seal Type | Unbalanced / Balanced Single Spring |
| Temperature | -20°C to +200°C |
| Pressure | Up to 10 Bar (150 PSI) |
| Face Materials | Carbon, Silicon Carbide, TC |
| Elastomers | NBR, EPDM, Viton, PTFE |
The single spring seal utilizes a single large, open-coil spring that resists clogging from solids or viscous fluids. The spring provides the necessary mechanical force to keep the primary sealing faces together, creating an effective barrier that prevents fluid from leaking out of the pump casing.
| Seal Type | Balanced / Unbalanced Multi Spring |
| Temperature | -40°C to +260°C |
| Pressure | Up to 25 Bar (360 PSI) |
| Face Materials | Carbon, Silicon Carbide, Tungsten Carbide |
| Elastomers | PTFE, Viton, Kalrez, FFKM |
The multi-spring seal incorporates several small coil springs arranged uniformly around the circumference of the seal face. This design ensures highly uniform face loading and maintains parallel seal faces even at high speeds, providing superior sealing performance in critical applications.
| Seal Type | Pre-assembled Cartridge Unit |
| Temperature | -40°C to +220°C |
| Pressure | Up to 30 Bar (435 PSI) |
| Metallurgy | SS316, Hastelloy-C, Alloy 20 |
| Face Materials | Silicon Carbide, Tungsten Carbide, Carbon |
A cartridge seal is a completely self-contained unit consisting of the seal faces, gland plate, sleeve, and springs all pre-assembled and preset at the factory. It slides easily onto the pump shaft as a single piece, eliminating installation errors, measuring, and setting of spring compression.
| Seal Type | Outside Mounted PTFE Bellow |
| Temperature | -20°C to +120°C |
| Pressure | Up to 5 Bar (75 PSI) |
| Face Materials | GFT, Ceramic, Silicon Carbide |
| Bellow Material | Pure Virgin PTFE |
The Teflon (PTFE) Bellow Seal is designed for extremely corrosive applications. It mounts externally on the pump shaft, ensuring that only the PTFE bellow and the seal faces come into contact with the aggressive chemical media, keeping the metallic springs and hardware safe from corrosion.
| Seal Type | Top/Bottom Entry Double Seal |
| Temperature | -30°C to +250°C |
| Pressure | Full Vacuum to 25 Bar |
| Shaft Size | 25mm to 150mm |
| Cooling | Integrated Cooling Jacket available |
Agitator seals are specially engineered dry or wet-running double seals used in reactors and mixers. They feature heavy-duty bearings to handle the high radial runout and shaft deflection typical of large agitators. A barrier fluid system is often used to ensure zero emissions of hazardous vapors.
| Available Spares | Impellers, Shafts, Sleeves, Casings |
| Materials | Cast Iron, SS304, SS316, Bronze, Duplex |
| Compatibility | ANSI, API, ISO Standard Pumps |
