On internet, I find Diaphragm Hand Pumps in Delrin. Why do not you offer it?
Delrin is an engineering plastic which offers good strength, but not as much as a metal does. As we offer pumps in Cast Iron and in SS 316, we do not lack in any application, which a pump in Delrin can perform and a model from our range cannot. For chemicals, polypropylene is a far better choice than Delrin is. So application wise, we offer a far wider choice, than a pump in Delrin does.
