DFY
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.
