S-Series

Product catalog summary

Introduction
The document is a technical catalog for the S-Series screw vacuum pumps by Elmo Rietschle, emphasizing their dry, contact-free operation that eliminates the need for lubrication in the pumping chamber, thus preventing process contamination.

Specifications
The S-Series includes models S-VSA, S-VSB, and S-VSI, capable of achieving vacuums up to 0.05 mbar (abs.) and operating across a wide pressure range. These pumps feature a rugged design with synchronized screw rotors, oil-lubricated gearboxes, and mechanical seals. Cooling is achieved through water circulation.

Applications
The pumps are suitable for industries requiring clean, oil-free vacuum processes, including chemical, pharmaceutical, food, packaging, and electronics. Applications include distillation, drying, coating, and vacuum metallurgy.

Product Overview
- S-VSA TWISTER: Suction capacities from 105 to 720 m³/h, suitable for solvent recovery and drying processes.
- S-VSB TWISTER: Capacities from 80 to 650 m³/h, designed for chemical and pharmaceutical industries, with ATEX compliant versions.
- S-VSI TWISTER: Capacities from 100 to 360 m³/h, ideal for industrial applications without aggressive gases.

Operating Principle
The screw vacuum pump operates with two parallel screw rotors that rotate in opposite directions, compressing gas in the pump housing. The design ensures efficient gas compression and discharge, with cooling facilitated by a water-cooled outer chamber.

Selection Data
The catalog provides detailed selection data for each pump model, including suction capacities, end vacuum levels, motor specifications, and cooling requirements.

Accessories
Various accessories are available, such as vacuum connections, exhaust outlets, cooling water inlets and outlets, and oil management components.

Specifications and Motor Ratings
The document outlines specifications for Gardner Denver's vacuum pumps, specifically the S-VSB TWISTER and V-VSB series, operating at both 50 Hz and 60 Hz frequencies. Motor versions vary with voltage specifications of 230/400 V for 50 Hz and 380/660 V for 60 Hz. Noise levels and maximum weights are provided for each model.

Procedures
Includes selection diagrams for both 50 Hz and 60 Hz operations, detailing suction capacity and end vacuum pressure. Maintenance instructions highlight the ease of servicing due to non-contact operation and corrosion-resistant coatings.

Standards
Specifications adhere to PNEUROP standards, with a tolerance of ±10%. Dimensions and current drawn may vary, noted as subject to request.

Recommendations
Pumps are recommended for solvent recovery and drying processes due to low running temperatures and corrosion-resistant coatings. Accessories such as vacuum tight suction filters, vacuum gauges, and soft starters enhance functionality.

Key Data from Tables and Diagrams
- Nominal capacities for 50 Hz range from 80 to 500 m³/h, and for 60 Hz from 100 to 650 m³/h.
- Motor ratings for 50 Hz range from 3.0 to 15 kW, and for 60 Hz from 3.6 to 18 kW.
- Average noise levels range from 72 to 80 dB(A) depending on the model and frequency.
- Maximum weights range from 230 kg to 750 kg.
- Cooling water consumption varies from 120 l/h to 1200 l/h.

Accessories
Lists various accessories including vacuum tight suction filters, vacuum gauges, soft starters, and non-return valves, detailing configuration options and flow rates.

Specifications and Motor Ratings
Provides detailed specifications for motor ratings and fixing options for motor flanges, including power ratings (kW) and associated part numbers.

Accessories and Control Devices
Lists accessories such as motor starters (ZMS) with specific amperage ranges and dimensions, emphasizing motor protection switches to prevent overload.

Lubricants
Specifies various oils for vacuum pumps and compressors, detailing properties like viscosity, density, flash point, and pour point.

Non-return Valves
Describes non-return valves (ZRK) designed to prevent backflow in compressors and vacuum pumps, suitable for pressures up to 3 bar and vacuum up to 5 mbar.

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

Conditions of Sale and Export Regulations
Outlines general and supplementary terms of sale and delivery, noting no export permits required under current regulations.

Quality Assurance and Standards
Elmo Rietschle products are ensured high quality through a comprehensive quality assurance system, complying with ISO 9001 and 14001 requirements.

Global Presence
Gardner Denver, the parent company of Elmo Rietschle, has a global presence with manufacturing and service locations in major industrial countries and a network of over 100 distributors.

Product Range and Capabilities
Outlines the operating range of Elmo Rietschle products, including pressure and vacuum capabilities, and volume flow rates, highlighting diverse applications and capabilities.
