Transfer Pumps
How To Choose Your Pump According to Chemical
G Series
'G' Series Self-Priming Centrifugal pumps - the self-priming ability,
chemical resistance,
light weight and basket strainer make this an ideal chemical
transfer,
waste treatment, emergency/backup
or filter pump. It is made in either Noryl
or
Ryton®,
providing a maximum range of chemical resistance.
| Available with 316 stainless steel, Hastelloy® C or titanium internal hardware or complete non-metallic solution contact |
| Large cover makes initial priming and removal of the strainer quick and easy |
| Will reprime to 15 ft. (4.6m) |
| Flow rates: to 100 GPM or 73 ft. TDH @ 60 Hz (330 LPM or 15m @ 50 Hz) |
| Shaft sleeve is same material as pump |
| Combination of 2"/1 1/2" NPT connections (BSP threads available for Noryl pump only) |

Magnetic Coupled
Magnetic Coupled, Seal-Less Centrifugal pumps are molded from
non-metallic
corrosion
resistant material. They can be constructed to accommodate
a wide variety of
applications
such
as photoprocessing, water & waste treatment,
semiconductor,
industrial
chemical processing,
high purity DI & RO water, paper & pulp chemical processing, fume scrubbing and plating.
