Clean Up Asphalt Pumping with Viking O-Pro Seals and 1224A-ASP Series™ and 1324A-ASP Series™ Pumps

Viking Pump is the market leader in pumping asphalt, pitch, residual oils, bunker oils, bitumen, and other materials which must be heated to prevent solidifying. Despite many technical advances over the last century shaft sealing for asphalt pumps has remained largely unchanged, relying on leaky packing. With the introduction of their patent-pending O-Pro seals and the ASP1 and ASP2 Asphalt pumps, Viking offers an innovative solution. Finally, there is an option for asphalt other than leaking packing! Geiger is excited to bring these revolutionary products to our customers in the Mid-Atlantic.

O-Pro: Superior Sealing for Asphalt Pumps

Asphalt pumps were traditionally sealed with packing, which must have some leakage. Cartridge lip seals and mechanical seals have also been used with asphalt, but are still prone to leakage and catastrophic failure and require frequent maintenance.    

What Makes O-Pro Seals Different? 

O-Pro seals use multiple O-rings together with a lubricating grease to extend seal life. An O-ring or gasket provides a static seal, while two dynamic O-rings seal to the shaft. The area between the O-rings is filled with grease, which provides constant lubrication to the dynamic seal.
