PFD4/PFS4 – OPERATING INSTRUCTIONS

∙PFD4 325 or PFS4 325: incorporates a flanged fitting PN10 DN25.

Both the inlet and outlet fittings can be turned over if necessary, by loosening the nuts on the inlet and outlet manifolds (P/N 2430M or 2435M, Mark G). For the suction manifold, first remove the base plate of the pump (P/N 2492). Re-tighten the nuts by hands.

If your pump is marked “W”, and you wish to change the side of the inlet and/or outlet manifolds, you must absolutely change the PFA seals (washers, P/N 2592, Mark F) located deep in the groove at the same time. Proceed as follows:

1)Remove the washers (with an air spray gun),

2)Fit the new washers in their grooves (a set of exchange seals is supplied with the pump: P/N WWES KIT S4),

3)Install and tighten the manifolds with a strap wrench (while tightening, you may here a bang).

III.4 –Tests and controls

Before commissioning the pump, we recommend to test it dry with a supply pressure of 72.5 PSI (5 bar) to ensure the system works correctly (See III.3.1 for the correct connections).

If the pump is cycling too quickly, reduce the speed by adjusting the needle valve.

Before using the pump with chemicals, please check:

∙The manifold rings are tight (tighten by hand),

∙The body tie rod nuts are tight. Because of the material of these tie rods, tightening of couple must be controlled: we recommend 7 N.m. (Maximum is 10 N.m),

∙The air/nitrogen supply is dry, clean and between 29 and 72.5 PSI (2 and 5 bar),

∙The inlet and outlet fluid connections are correctly fitted and tight.

IV – Applications

IV.1 – Chemical compatibility

All PFD/PFS pump wetted parts are manufactured in TEFLON® PTFE and PFA and are suitable for pumping even the most corrosive concentrated chemicals: H2SO4, HNO3, HF, H3PO4, HCl, NH4OH, KOH, NaOH, CH3COOH, TMAH, H2O2...

The viscosity of the fluid must be less than 1000 cpo.

PFD/PFS pumps can pump liquids containing particles up to 0.02” (0.5 mm). Very abrasive liquids are not recommended.

Please call either the factory or your local distributor if you require information on chemical compatibility.

IV.2 – Contamination

The “all plastic” construction of the PFD/PFS pump ensures no ionic contamination of the chemical, even if there is a bellows failure.

Due to the low frequency and amplitude of the bellows pump, SGPPL ASTI guarantees a lower level of particle contamination when compared to a diaphragm pump.

IV.3 – Temperature range

The PFD/PFS pump can handle liquids from 32°F (0°C) to +212°F (100°C). When the fluid temperature is greater than 140°F (60°C), you must frequently check that the manifold rings are fully tight and that supply pressure is less than 43.5 PSI (3 bar).

For special applications, call SGPPL ASTI or your local distributor.

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.
