TANDEM PUMPS

Tandem configuration pumps combine any two modular pumps into a single unit. This configuration can yield up to three different displacements and is available with common or separate inlets and outlets. Reservoirs and mounting plates can be added to complete the package. All of the same standard and optional features from the 500/550 series are included in the tandem pumps. A special handle assembly is provided as standard to operate both pumps or just one. Triple and quadruple units are also available consult the factory for details.

STANDARD FEATURES

• All steel construction for rugged use.
• Rod wiper (except 1-1/2" bore) to exclude dirt.
• All o-ring seals – no fiber or metal seals to leak.
• Self-retained release screw, which cannot be accidentally removed.
• Capable of operating in any mounting orientation.
• Heat treated pins and linkages for extended life.
• Ground pistons to prevent seal extrusion.
• Nitrotec treated pistons for corrosion resistance.

OPTIONAL FEATURES

• Optional seals for pumping alternate fluids.
• Manifold mounting for inlet and/or outlet.
• Operating handle length – 18 or 36 inches for various handle forces.
• Custom designs for your particular application requirements.

TANDEM ORDERING INFO

Standard sizes are 030 for 3/8, 040 for 1/2", 050 for 5/8", 060 for 3/4", 080 for 1", 120 for 1- 1/2", 124 –125-126 are for two stage configurations. Any two size pumps can be combined, maximum pressure rating is a function of the final configuration, consult engineering for rating. When operated together the displacements and handle forces are cumulative, add for total displacement and force.

Standard configuration is for a common inlet and common outlet, if required a common inlet with separate outlets is available – consult factory.

500 Series dimensional data is available in the 500 Series Catalog.
