C-Series

Product catalog summary

Introduction
The document is a technical catalog for Gardner Denver's C-Series claw vacuum pumps, compressors, and pressure-vacuum pumps. It emphasizes the efficiency and economic benefits of these dry-running, contact-free systems that use internal compression for energy savings.

Specifications
The C-Series includes claw vacuum pumps (C-VLR), claw compressors (C-DLR), and claw pressure-vacuum pumps (C-KLR). These systems offer vacuum levels up to 50 mbar (abs.) and pressures up to 2.2 bar, with pressure-vacuum pumps achieving underpressure up to -0.6 bar and overpressure up to +1.0 bar.

Innovative Claw Technology
The claw technology features high-precision, contact-free rotors synchronized by precision gears, allowing for dry, wear-free compression without sealing fluids. Explosion-proof and ATEX-compliant versions are available.

Advantages
The C-Series is noted for high efficiency, low maintenance, and robust design, featuring integrated air cooling, low noise levels, and patented triple lobe rotors that combine pressure and vacuum in one stage.

Applications
These systems are suitable for industries such as chemical, environmental engineering, industrial applications, medical, packaging, and woodworking, used for gas compression, drying, dust extraction, and more.

Product Overview
The C-VLR ZEPHYR vacuum pumps have capacities from 60 to 1,000 m³/h, C-DLR ZEPHYR compressors range from 60 to 600 m³/h, and C-KLR ZEPHYR pressure-vacuum pumps offer capacities from 80 to 140 m³/h. All models feature integrated air cooling and variable speed drives.

Operating Principle
The claw pumps operate on a static compression system with two rotors compressing gas internally by reducing volume, achieving high differential pressures with efficiencies over 60%. Cooling air manages heat generated during compression.

Selection Data
Detailed selection data for the C-VLR range includes vacuum levels, capacities, motor specifications, and dimensions. Accessories like non-return valves and vacuum-tight suction filters are listed.

Acoustic Enclosures
Designed to reduce noise levels by at least 10 dB(A) without affecting operating temperature, suitable for sizes 250 to 500, and can be retrofitted. Made of painted sheet steel, weighing 325 kg.

Soft Starter (ZAD) & Motor Starter (ZMS)
The soft starter reduces mechanical stress and peak loads during motor start-up, while the motor starter protects electric motors from overloading with a thermal overload feature.

Oils and Grease
Five types of oils are available, including mineral, synthetic, and food-grade options. A grease gun is available for regreasing bearings, with specific greases recommended based on the pump or compressor.

Valves
Non-return valves prevent backflow in stalled pumps or compressors, designed for pressures up to 3 bar and vacuum up to 5 mbar. Vacuum and pressure regulating valves adjust suction pressure and limit maximum vacuum or pressure, recommended with a pulsation damper.

Pulsation Damper
Used to significantly reduce pulsation caused by the expansion of precompressed gas, with specifications provided for different models.

Conversion Tables
Includes conversion tables for pressure, suction capacity, power, mass, and length, along with temperature conversion formulas and pressure conversion examples.

Conditions of Sale and Delivery
General and supplementary terms and conditions apply, with products not requiring an export permit under current German and US regulations.

Certified Quality
Emphasizes high quality supported by a quality assurance system compliant with ISO 9001 and 14001 standards.

Gardner Denver Locations
Lists global locations to ensure proximity to customers for fast response times and local support.

Operating Range
Charts and graphs illustrate the operating range of Elmo Rietschle products, including pressure and volume flow capacities for different types of pumps.

Einleitung Introduction Claw Vacuum Pumps, Compressors and Pressure-Vacuum Pumps Our dry running C-Series generates contact free vacuum or compressed air efficiently and economically due to the principle of internal compression. This leads to considerable energy savings compared to the traditional rotary lobe design without internal compression. The overhung rotor design in all sizes up to 300 is another outstanding feature of this technology. Gas tight versions with reduced leakage rates are available. We hold the patent on the newly designed triple lobe rotors with intermediate charging of...
