The self-priming Series 'G' Pump is made in either Noryl or Ryton, providing a maximum range of chemical resistance. It is available with 316 stainless steel, internal hardware or completely non-metallic solution contact. The pump comes standard with 304 stainless external hardware. The pump is protected with a basket-type strainer in either polypropylene or ECTFE. The large cover makes initial priming and removal of the strainer quick and easy.
