Surge Tank for Medium Volume Hi-Flo Pumps

Part No. Inlet/Outlet Max Inbound Fluid Max Delivery Wetted Parts
220157 1 x 1 1⁄4 npt(f) 600 psi 15 gpm Carbine, SST, UHMWPE, Viton, PTFE
233736* 3/4 BSPP(f) 360 psi NA SST, PTFE

*Waterborne compatible


Surge Tank for High Volume Hi-Flo Pumps

Part No. Description Inlet/Outlet Max WBR Max Delivery Material
238986 Surge Tank 2 npt(f) 300 psi 20 gpm SST, PTFE
238987 High-Flo Surge Tank 2 npt(f)* 300 psi 20 gpm SST, PTFE
238988 High-Flo Surge Tank 1-1⁄2 npt(f)* 300 psi 20 gpm SST, PTFE
218509 High-Flo Surge Tank 2 npt(f)* 300 psi 20 gpm Carbide, SST, UHMWPE, Viton, PTFE

*Sanitary Tri-Clamp compatible
Note: Maximum flow rates are recommended maximums for peak performance. Exceeding these values reduces the surge tanks ability to dampen pulsation.

Max. Inbound Fluid Regulated Pressure Max Delivery Wetted Parts
223883 2 in sanitary
clamp
300 psi 0-260 psi 20 gpm 304, 316, 316L and 17-4 PH SST, carbide, PTFE
235282 1-1/2 npt(f)
sanitary clamp
300 psi 0-260 psi 20 gpm 304, 316, 316L and 17-4 PH SST, carbide, PTFE

Includes air pilot port 1⁄4 npt(f) max, 100 psi
Note: For material viscosities less than 5 centipoise, regulator should be tested by customer before making multiple regulator installations. Very low viscosities regulation at low pressure may not be possible.
