5700 Series CycloPhram

Models 5730 metering pumps are of hydraulically actuated non-lost motion (amplitude modulated) diaphragm design. The unique method of actuation by means of a rotating plunger provides smoother, quieter operation. The design characteristics minimize back lash and shock loads to the process system.

Models 5730 are among the longest lasting pumps in the industry. These pumps will provide reliability in the heaviest workload environments, such as mining, nuclear plants, power plants and refineries/petroleum applications. These pumps meet API 675 standards.

Performance

Models 5730 offers maximum capacities from 350 gph up to 370 psig. The stroking length can be manually or auto-matically adjusted from 0-100%. The pumps are available with up to five stroking speeds. All models may be duplexed.

While the pump is running or stopped, the stroke length

may be manually adjusted from 0 to 100% by using the micrometer control. Internally, this moves a shift ring. The unique spring loaded rotating plunger is always extending or compressing. It displaces hydraulic fluid through the hollow center of the drive shaft and flexes the diaphragm for a smooth reliable performance. Repetitive accuracy is +1%.

Oversized main bearings support the drive shaft across a very short span, maximizing mechanical efficiency and ensuring long pump life.

An independent speed reducer allows for two separate oil reservoirs to match the requirements for both the hydraulic system using low viscosity oil and the gear drive using lubricating gear oil.

Materials of Construction

Model 5730 can be supplied with Alloy 20, Hastelloy C, 316 Stainless Steel or Polypropylene (max. 150 psig) wetted ends. All diaphragms and seals are available in PTFE, suited for the most demanding chemical duty applications.

A rugged cast iron housing contains a high performance rotating plunger submersed in an oil reservoir. The plunger

is the only reciprocating part in the entire hydraulic drive mechanism.
