Scot 3″ x 3″ Cast Iron Pressure Seal Pump (Viton) – PSP303


Ships LTL

Pressure seal pumps are designed for use with products that do not provide enough lubrication for the seal or the product being pumped is abrasive. The standard Viton seal is enclosed in its own chamber that is filled with an anti-freeze/water solution and pressurized to 120 PSI. Scot pressure seal pumps are recommended for products such as micro-encapsulated herbicides and fertilizer suspensions which tend to cause premature seal failures on standard pumps.
