The Chem-Tech 100 and 200 series pumps are now coming with acrylic heads again. Its been about 1 1/2 years sense Pulsafeeder changed from acrylic heads to PVC heads because of vendor problems. Many customers were upset because they liked viewing the bouncing ceramic ball indicating that there was chemical being injected. The vendor problem has been corrected and now the pumps are being supplied with the clear heads.
