Strongest Pump Shaft - Smith & Loveless pumps boast the largest pump shaft in the industry. Larger shafts have less shaft deflection, which is a determining factor in the life of the mechanical seal.
Streamlined for Ease of Maintenance - Full access to the volute and suction elbow is possible by merely removing the capscrews and raising the entire rotating assembly.
Superior Mechanical Seal Design - Smith & Loveless vacuum primed pumps are equipped with a single bronze mechanical seal, which allows better heat dissipation and eliminates the need for a seal water filter system. Because bronze is a non-ferrous material, it prevents abrasive iron oxide from forming in the seal assembly. It also prevents seal pieces from rusting together and impeding maintenance. Smith & Loveless pumps are designed so that the mechanical seal can be accessed and replaced in less than 30 minutes. All seals will eventually wear out, but proper maintenance extends seal life up to 7 years on average.
Impeller Design - Equipped with heavy cast iron, balanced impellers. Impellers are custom trimmed for each application. Only vanes are trimmed; shrouds are left full diameter to prevent solids and stringy matter from accumulating around the shaft. The tight clearance between the impeller and front head minimizes recirculation, improving efficiency. The shaft and impeller bores are tapered for easy removal.
