SPEW SVP Sliding Vane Pump

SPEW SVP Sliding Vane Pump blends rugged performance with premium presentation: a compact, positive-displacement design that self-primes fast, delivers smooth, low-pulsation flow, and maintains output across a wide viscosity range—from thin solvents to heavy lube oils. Carbon/compound vanes automatically compensate for wear to preserve volumetric efficiency, while strong suction lift and reversible operation make loading/unloading seamless. An integral, adjustable relief valve safeguards the line, and the service-friendly layout keeps downtime to a minimum. Pair with a VFD for precise metering, choose materials/seals to match your media, and specify ATEX/IECEx options for hazardous areas. SVP by SPEW—reliable, gentle, and efficiency-driven transfer for fuels, lubricants, and process chemicals.

Features

  • Self-priming & strong suction: Fast air evacuation; reliable suction-lift for tank truck, underground tank, and transfer duties.
  • High efficiency across viscosities: Handles ~0.2 to 100,000+ cSt with minimal slip; maintains flow as pressure rises.
  • Low pulsation, smooth flow: Fewer pressure spikes than gear pumps; better for meter accuracy and downstream instrumentation.
  • Gentle on product: Lower shear than gear pumps; protects lube oils, polymers, fuels, and additives.
  • Reversible operation: Full-rated flow in either direction by reversing rotation—ideal for loading/unloading.
  • Dry-run tolerant (short duration): Carbon/graphite vanes provide brief dry-run survivability for line clearing and priming.
  • Built-in safety: Integrated relief/bypass valve protects pump and line from over-pressure.
  • Serviceable design: Front pull-out construction on many models; vanes are a low-cost wear item, replaced in minutes.
  • Compact footprint: High power density and simple drive options (motor, VFD, PTO, hydraulic, engine).

Structure

  • Pump body/cam: Cast iron, ductile iron, carbon steel, or stainless steel for corrosive/food-grade service
  • Vanes: Carbon/graphite (standard), polymer composite, or specialty grades for high temp/chemical resistance
  • Shafts/bearings: Alloy steel / stainless shafts; anti-friction bearings with robust lubrication path
  • Sealing:
    • Mechanical seal (single, double, or cartridge) with flush/plan options
    • Packed gland for heavy-duty or dirty service
    • Mag-drive available on select models for zero emissions
  • Ports: NPT, BSP, ANSI/DIN flanges; inline or right-angle configurations
  • Safety: Integral adjustable internal relief valve; external recirculation on request; ATEX/IECEx options for hazardous areas
