Description

The SNP Series is Blackmer's Stainless Line of sliding vane pumps, built from 316 stainless steel on all significant wetted parts for handling corrosive or caustic liquids. Sliding vanes and reversible carbon discs are nonmetallic, which reduces friction and eliminates the galling that can occur in all-stainless vane pump designs. The line spans 5 sizes with port sizes from 1-1/4 in to 3 in, flows from 3 to 275 gpm, temperatures to 350 degrees F, and relief valve pressures to 150 psi. Heating jackets are available on select models to protect bearings and seals from cold start-up on high-viscosity products.

  • 316 stainless-steel construction with metalized carbon sleeve bearings and non-metallic vanes for longer life with corrosive products
  • Nonmetallic sliding vanes and reversible carbon discs reduce friction and eliminate galling
  • Shaft stuffing box accommodates most standard aftermarket mechanical seal configurations
  • Jacketed pump head option available on SNP1.25, SNP1.5, and SNP2 for high-temperature start-up
  • Adjustable relief valve protects the pump against excessive pressures (integral relief valve standard on SNP3A)
  • Self-adjusts for wear to maintain flow rates, with excellent self-priming and dry-run capabilities
  • Easy maintenance: vanes can be replaced without removing the pump from the piping system

Configuration Options (call to order)

The options below are not selectable online. To configure any of these for your order, call (262) 646-4500.

Option Values Notes
Vanes Duravane (Std, code 4); EC Laminate / extra clearance (code 6) Laminate adds $437 (SNP1.25/1.5), $327 (SNP2), $509 (SNP2.5), $545 (SNP3A)
Rotation Right-hand/CW (Std, code 1R); Left-hand/CCW (code 1L) No charge either way
Relief Valve No Relief Valve (Std, code 0, SNP1.25-SNP2.5 only); Bolt-on Relief Valve (code 1, +$669, SNP1.25-SNP2.5); Integral Relief Valve (Std on SNP3A only, no NRV option on that model) SNP3A always ships with its integral relief valve
Relief Valve Spring Stainless steel spring ranges 25-50 / 51-75 / 76-100 / 101-150 psi (by model); all $0 Call to specify your required pressure range.
O-Rings PTFE (Std, code 3/0) Only value offered on this sheet
