Sliding Vane Pumps

• Blackmer’s sliding-vane pumps use a unique vane design that self-adjusts for wear — maintaining consistent volumetric performance over time, unlike gear or lobe pumps.
• They provide excellent self-priming and can run dry, making them ideal for transfer, loading, or unloading of liquids and vapour-liquid mixtures.
• Their slow internal velocities support a wide viscosity range — from thin liquids to viscous or difficult-to-pump fluids — and make them suitable for abrasive or shear-sensitive media, or for applications with entrained gas/vapor.

Sliding vane models cover everything from light-duty and general transfer to heavy-duty applications, with a variety of series adapted for petrochemicals, fuels, chemicals, LPG, and more.

Internal Gear, Centrifugal, Screw & Regenerative Turbine Pumps

• Internal Gear Pumps — Offer consistent volumetric output and are well-suited for viscous, hard-to-seal, or high-value fluids. Effective in chemical, oil & gas, coatings, and other industries where fluid properties are challenging.
• Centrifugal Pumps (ANSI-class, cryogenic) — Designed for high-volume, severe-duty, or special-service tasks — including cryogenic or high-pressure duties when required by the process.
• Screw Pumps — Self-priming and robust, performing reliably under a wide range of temperatures, pressures, and viscosities. Good for demanding industrial environments.
• Regenerative Turbine Pumps — Blending the pressure characteristics of positive displacement pumps with the flexibility of centrifugal designs; useful when transferring low-viscosity but high-pressure fluids, or fluids with entrained vapour.
• Reciprocating Gas Compressors — Engineered for gases (like LPG, natural gas, refrigerants) and liquefied-gas transfer or vapour-recovery tasks, offering high efficiency, reliability, and suitability for demanding gas-handling applications.

• Consistent performance: Self-adjusting vane technology maintains flow and efficiency over time.
• Handles difficult fluids: Suitable for thin liquids, viscous products, volatile chemicals, abrasive slurries, and fluids with entrained vapour.
• Wide technology range: Sliding vane, internal gear, centrifugal, screw, turbine pumps and gas compressors cover virtually any liquid or gas-handling need.
• Proven reliability: Over a century of engineering experience across chemical, energy, transport, and industrial sectors.
• Low lifecycle cost: Efficient hydraulics, robust designs, and easy maintenance help reduce overall operating costs.
