E series

Product catalog summary

General Features
2DRE Rotary flow dividers and flow equalizers are designed to handle high pressure between sections when used as pressure intensifiers. For specific working conditions exceeding 80 l/min inlet flow, consultation with the technical department is recommended.

Working Conditions
- Maximum continuous pressure: 200 bar / 2900 psi
- Maximum peak pressure: 280 bar / 4000 psi
- Contamination class: NAS 1638 and ISO 4406
- Filtration index achieved with filter ßx =75
- Minimum operating fluid viscosity: 12 mm²/sec
- Maximum starting viscosity: 800 mm²/sec
- Suggested fluid viscosity range: 17 - 65 mm²/sec
- Fluid operating temperature range: -15 to +85 °C
- Hydraulic fluid: mineral oil

Specifications
The document provides a detailed table of specifications for various 2DRE models, including displacement, maximum outlet pressure, speed, and flow per section. Each model has specific parameters for bar, psi, and flow rates.

Displacement Selection and Calculation Examples
To equalize flow, maintain speed within the suggested range with a maximum Δp of 50 bar (725 psi) between stages. The document provides formulas and examples for calculating flow equalization and pressure intensification. For instance, supplying two cylinders with equal flow requires an inlet flow of 60 l/min, and the displacement should be chosen based on the highest rpm within the recommended speed area.

Flow Equalizer and Divider
Examples illustrate how to use flow equalizers and dividers for different flow requirements. The flow equalizer example shows supplying two cylinders with the same flow, while the flow divider example demonstrates supplying two cylinders with different flows.

Pressure Intensifier
The rotary flow divider's working principle allows it to function as a pressure intensifier by transferring energy from a lower pressure outlet line to a higher pressure stage, effectively increasing the outlet pressure without energy dissipation.
