500 Series Vertical Sump Pumps

Pump

The Series 500 is a centrifugal type pump fitted with a 2” discharge. It is fitted with a semi-open impeller accurately machined and balanced for smooth, quiet operation. Also available in all iron and 316 stainless steel.

Mechanical Shaft Seal

Series 500 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.

Pump Lubrication

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.

Shaft Column Pipe

The models 500S and 500AI are manufactured with schedule 80 hot dipped galvanized steel as standard.

Shaft

Size 5/8″ high accuracy, grade 1215 steel that is turned, ground and polished. Shafts are also available in stainless steel.

Discharge Pipe

The pump is manufactured with schedule 40 hot dipped galvanized steel as standard.

Motor Support Bracket

The heavy cast pedestal is accurately machined with an integral bracket to support the discharge pipe, house the upper bearing and align the motor. It is suitable for motor frames 56C – 184C.

Bearings

The upper bearing is a permanently lubricated and sealed precision thrust ball bearing. The lower and intermediate sleeve bearings are self lubricated.

Floor Plate Suspension Cover

Heavy duty 20” diameter adjustable cover is standard (Type A). TRAMCO will fabricate covers to match existing pumps.

Motors

The motor and pump shafts are connected by a flexible coupling that allows the motor to be easily removed without distributing the pump and piping. The motor can be detached by simply removing four bolts.

Strainer

Made of heavy cast iron construction, the strainer is sized for solids the pump will pass. It is also available as a pump stand (Type C)

Float Control (Optional)

Heavy duty pedestal or motor mounted float switch is available. Float ball is stainless steel.

Basin Cover (Optional)

Heavy duty basin cover capable of supporting vertical suspended pumps and motors. Covers are available for simplex, duplex or other configurations.
