The Model DFY is an incredible vertical sump and process pump. The DFY, although not 100% interchangeable parts, can replace the Goulds 3171 in industrial processes, sump drainage, and for corrosive liquid applications. This pump is simple to install, operate, and maintain. The total cost of ownership is significantly reduced when comparing to the Gould's 3171.
DFY series corrosive vertical submerged pumps are single-stage, single suction, long-shaft submerged centrifugal pumps. lt has high efficiency, power saving, operating liability. lt can pump corrosive medium which has solid particles and wearable materials.
The medium temperature varies from 0 °C to 105 °C. Heat preservation closed cover and low temperature wearable guide bearing are used when the temperature of medium is from -20 °C to 0 °C, cooling closed coverand high-temperature wearable guide bearing are used when the temperature of medium is from 105 °C to 180 °C. This condition must be stated when ordering.
lf medium has little solid particle, sliding bearing should be outer-lubricated bearing, which shall be stated clearly when ordering, (water and other allowed medium whose outer pressure is ovar 0.2 MPa.).
Operating pressure is designed at 1.6MPa.
Performance range: Capacity: 1. 6 -2600m ª/h, head: 5-132m.
The materials contacting with liquid can be selected as cast iron (H),cast steel,1Cr18Ni9Ti(B), 1Cr18Ni12Mo2Ti(M), 304. 304L, 306, 306L, 904, Lewmet Alloy, 20# Alloy according to different medium.
