PFD4/PFS4 – OPERATING INSTRUCTIONS

Thank you for choosing our SAINT-GOBAIN PERFORMANCE PLASTICS ASTI AstiPure™ model PFD4 pump, series 3 (or PFS4: slurry applications).

I – General

I.1 – Introduction

The model PFD/PFS is a pneumatically operated TEFLON® pump. There are no internal or external metal parts.

The pump is designed for handling corrosive, inflammable, and sterile fluids. It meets the requirements of the semiconductor, pharmaceutical and chemical industries.

I.2 – Materials

All wetted parts are manufactured in TEFLON® PFA HP and PTFE.

Other parts are made of high-tech plastics such as PVDF, PEEK etc.

There are no metal parts.

I.3 – Operation

The pump is pneumatically operated; two bellows joined by a central shaft reciprocate horizontally. The suction and delivery strokes alternate from one side of the pump to the other.

The pump is self-priming and has four balls, which seat on lip seals (check valves).

The pumping frequency of a bellows pump is much slower than an equivalent diaphragm pump and results in an extended life for the bellows.

Pulsation dampers with wetted parts in TEFLON® PFA and PTFE are available as an option. This dampens the pulse by approximately 65 to 80%.

The pulsation damper for the PFD4/PFS4 pump is AMC4/AMS4.

Saint Gobain Vidros PFS4, PFD4 manual General, II Quick checklist

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.
