Standard SNP pumps are constructed with self-lubricating sleeve bearings and PTFE impregnated shaft packing. Options for models through 232-inch port size include jacketed heads for circulation of steam or hot oil when handling viscous fluids and removable 2-way relief value which permits either back-to-tank or internal bypassing. All SNP pumps will handle fluid viscosities in excess of 20,000 ssu (4,250 cSt) and are equipped with removable drain plugs for complete self-drainage. ANSI compatible flanges on sizes 232-inches and weld flanges on 3-inch size. Application Blackmer SNP pumps are typically used in handling a variety of corrosive or caustic fluids such as acids, brines and liquid foods such as sugars, syrups, beer, beet juice, cider and flavor extracts. Many pumps used in corrosive service use stainless steel for all parts in contact with the fluid. However, the resulting metal-to-metal contact often causes galling and seizing that can become a major maintenance problem. While Blackmer uses 336 stainless steel on all significant wetted parts, sliding vanes and reversible carbon discs-are non-metallic. This reduces friction and eliminates galling. Benefit Utilizing Blackmer's unique sliding-vane design, the positive displacement rotary pumps offer the best combined characteristics of sustained high level performance, energy efficiency, trouble-free operation and low maintenance cost. The non-metallic parts increase pump life and durability and allow the pump to withstand occasional dry running. SNP1.5 Cutaway SNP3 Cutaway How a Rotary Vane Pump Works www.blackmer.com
