Download Spec Sheet

The 500 Series is our most popular and versatile model.  It is available in various types of materials and configurations.  Can be configured for suspension plate or self supporting stand.  Common uses of the 500 Series are sump and condensate (available with high thrust bearing for temperatures over 190 degrees F)  applications.  Available in 1-1/2" and 2" discharge sizes.  Flows up to 130 GPM and heads of over 50'.


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.
