TONKAFLO SPECIFICATIONS

The Tonkaflo pumps covered in this instruction manual are the higher capacity SS5500,
SS8500, SS12500, SS23000, and SS24000 Series pumps. These five series of pumps cover a
flow range of 20 - 300 gpm (4.5 - 68 m
The capacity and discharge pressure can be increased by operating pumps in parallel or
series, respectively. There is no maximum limit on capacity when operating Tonkaflo pumps
in parallel. When operating pumps in series, a maximum discharge pressure of 1000 psig (69
barg) may be achieved with optional high pressure construction on the downstream pump.
With inlet pressures greater than 200 psig (13.8 barg) and less than 400 psig (27.6 barg),
optional high-pressure mechanical seals should be used.
