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
3
/h) with single-unit pressures up to 650 psig (44.8 barg).
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.

NOTE:
There must be adequate flow through the pump to prevent excessive heat build-
up at all times.
