3500 Series Industrial Sump Pump
TRAMCO’s Series 3500 Vertical Sump Pumps are engineered and precision built for years of dependable service. Quality materials and construction, together with a mechanical shaft seal design, allow continuous operation in temperatures up to 200° F.
The Series 3500 is a centrifugal type pump fitted with a semi-open impeller accurately machined and balanced for smooth, quiet operation.
Mechanical Shaft Seal
Series 3500 pumps are fitted with a mechanical shaft seal which prevents the liquid being pumped from entering the lower sleeve bearing while retaining the lubrication in the pump. Several seals are available to meet your application.
Tramco’s lubrication system provides continuous lubrication to shaft, self lubricated intermediate and lower sleeve bearings. It eliminates the need for external grease lines or product lubricated sleeve bearings.
