Thank you for selecting a SAINT-GOBAIN PERFORMANCE PLASTICS ASTI model PFD1 AstiPure™
 
pump, series 2 (or PFS1: 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 PFD1/PFS1 pump is 
AMC1/AMS1.

II – Quick checklist 
 
II.1  – Shipment 
 
Pumps are cleaned and assembled in our clean room, then double sealed in plastic bags to ensure they 
are not contaminated in transit. They are then packed in cartons with Polyethylene protection.
