Compact Bellows Metering Pumps

Motors
Speeds

Standard motor speeds are 45.6 and 90 RPM at 60 Hz. Motors can be supplied in virtually any speed up to a maximum of 120 RPM.

Voltages
Standard voltages are 115V, 50/60 Hz, or 230V, 50/60 Hz. However, the following special voltages are also available: 12 and 24VDC, or 24VAC.

Designs
The standard motor is an open, shaded pole gearmotor. Motors are also available in steppers, and DC.

Options
Motors can be supplied with microswitches for stroke counting and cork brakes. Units without motors (pedestal models) are also available on some models.

Miscellaneous Options
Other options available for the compact bellows pumps include duckbill valves, miniature switches to count strokes, stainless steel mounting brackets and splash covers.

Poppet Valves and O-rings
The standard elastomers for the poppet valves and O-rings are EPT/EPDM and Viton®/Fluoroelastomer. These elastomers have historically been able to handle the vast majority of the applications in which we’ve been involved. However, Butyl, Hydrin, Kel-F®, Silicone and Nitrile can be supplied for chemicals requiring such materials.

Duckbill Valves and O-rings
Duckbill valves are required in those applications where heavy slurries and fibrous materials are being pumped. Heavy slurries should be flushed from the bellows before pump is shut down. Duckbill valves are available in the same elastomers as the poppet valves.

Valve Bodies
Standard valve body on the compact pump is a 90° valve body. Vertical and T-head valve bodies can be substituted on all bellows sizes except the 1/2″ bellows.

Pump Covers
In addition to the standard options listed, cover options can also include different wire or cord lengths and terminations, strain reliefs and ground wires.

Oscillating Pumps

Valve Styles
To modify the priming or performance characteristics of the pump, two valve options are available: poppet valve or 2-piece valve.

The poppet valve provides the best priming capability and more positively prevents backflow through the pump.

The 2-piece valve generally delivers higher flows than the poppet valve.

Note: Valves are utilized on the discharge side of the pump. However, to more closely meet a customer’s specifications, valves can be used on both the inlet and outlet side.

Tubing Connectors

  • 1/8″ – 3/16″ I.D. Tubing
  • 1/4″ I.D. Tubing
  • 3/8″ I.D. Tubing
  • 1/2″ I.D. Tubing

Coils, Leads and Terminals
Generally, electrical coils are available in 115V or 220V and 60 Hz. However, pumps have been supplied with 115V or 220V, 50 Hz coils, and with 12, 24, and 48 volt AC coils. In addition, coils can be constructed with different power capabilities to more effectively meet customer’s duty cycle needs.

Leads can be up to 6 feet long with any termination. Most common are 6 inch leads with 1/4 inch male spade terminals.

Mounting Options

  • Rubber Mount
  • Spring Mount with Base
  • Spring Mount

The oscillating pump can be provided with three mounting styles. The rubber mount design is more compact and less expensive; however, flow rate, priming capability and discharge head are lower than the spring mounted pumps. The spring mounted model is more efficient and transmits less vibration to the mounting structure.
