PFD4/PFS4 – OPERATING INSTRUCTIONS

II.2 – Reception

Upon receipt of the pump, please check that:

∙The carton has not been damaged in transit. If there is any visible damage, immediately contact the carrier.

∙The pump is not damaged. If there are signs of damage, you should report this immediately to SGPPL ASTI or your local distributor.

∙An operating instruction manual has been included in each package. Please request another copy if it has not been included.

III – Installation and operation

III.1 – Testing

All pumps are tested with DI water at the factory in our clean room for:

∙Maximum flow rate with no back pressure

∙Minimum flow rate with no back pressure

∙Flow rate with 58 PSI (4 bar) discharge pressure

∙Checked for leakage

III.2 – Set up

The pump must be installed horizontally as shown on general arrangement drawing (see appendix “APP 4 EXT”). This drawing also shows the overall dimensions of the pump etc.

The pump must be installed on its feet. If not, the check valves will not seat correctly and the pump may malfunction.

III.3 – Connections

III.3.1 – Air/Nitrogen connections

The pump must be connected to a clean dry air or nitrogen supply. On no account should the air/nitrogen supply be lubricated, oil or water droplets will cause the shuttle valve to malfunction. Minimum and maximum supply pressure must be between 29 and 72.5 PSI (2 and 5 bar).

For optimum pump operation, we recommend a supply pressure of 58 PSI (4 bar).

The ID of the tube supplying the dry air/nitrogen should not exceed 3/8” (10 mm). The tube length between the pump and on/off valve should be between minimum 10 feet (3 m) and maximum 19 feet (6 m).

When in aggressive conditions (acid vapors), it is advised to canalize outlet with a tube minimum ID 5/8” (15 mm).

The pneumatic on/off valve must be 3-way to ensure the shuttle valve on the pump resets itself when the pump is switched off. The flow control valve must be positioned before the 3-way on/off valve (see appendix “APP 4 CAB”).

A remote control box with on/off switch and a needle valve (P/N 24 000 04) is available as an optional extra.

III.3.2 – Fluid connections

The pump is self-priming. The inlet is at the bottom and the outlet at the top.

Two optional fittings are available:

∙PFD4 322 or PFS4 322: pump is supplied with flared fittings suitable for 7/8”x1” (22x25 mm) TEFLON® tube. The tube needs to be flared prior to fitting using SGPPL ASTI Forming Tool (P/N MF12228).

PFS4, PFD4 specifications

Saint-Gobain Vidros is a prominent name in the glass manufacturing industry, recognized for its innovative and high-quality products. Among its notable offerings are the PFS4 and PFD4 glass types, which are designed to meet the diverse needs of modern architecture, energy efficiency, and sustainability.

The PFS4 (Premium Float Solar) glass is specifically engineered for applications where solar control is crucial. It features a low solar heat gain coefficient, allowing buildings to minimize cooling energy consumption during warmer months. This glass type is particularly advantageous for large commercial buildings with extensive glazing areas. The PFS4 glass is also treated with advanced coatings that enhance its performance by reflecting unwanted solar radiation while permitting a substantial amount of natural light to enter, creating a comfortable and well-lit indoor environment.

On the other hand, the PFD4 (Premium Float Double) glass caters to energy efficiency and superior thermal insulation. This double-glazed solution offers enhanced acoustic performance and thermal resistance, making it an ideal choice for residential and commercial buildings in noisy or extreme climates. With its unique combination of air or argon gas fill between the glass panes, the PFD4 effectively reduces heat loss in winter and minimizes heat gain in summer, contributing to lower energy bills and reduced environmental impact.

Both PFS4 and PFD4 incorporate cutting-edge technologies that align with the global trend towards eco-friendly building practices. These glass products are manufactured using sustainable processes, and they fulfill stringent environmental standards. They not only ensure safety and durability but also promote reduced energy consumption and greenhouse gas emissions.

Additionally, the aesthetic appeal of both glass types cannot be overstated. Leaders in contemporary design often select these products for their clarity and ability to blend seamlessly into various architectural styles. The low-reflective quality of PFS4 combined with the noise reduction capabilities of PFD4 makes them versatile choices for any project.

In summary, Saint-Gobain Vidros PFS4 and PFD4 glass types stand out in the glass industry for their commitment to quality, innovation, and sustainability. Whether for enhancing energy efficiency, acoustic comfort, or aesthetic value, these products provide cutting-edge solutions that cater to the modern demands of architecture and construction. By opting for PFS4 and PFD4, builders and architects can ensure a harmonious balance between functionality and design, paving the way for more sustainable and beautiful structures.
