TONKAFLO SPECIFICATIONS

The Tonkaflo pumps covered in this instruction manual are the lower capacity SS500, SS1000,
and SS1800 Series pumps. These pumps cover a flow range of 1.5 - 18 gpm (0.34 - 4.1 m
with single unit pressure up to 700 psig (48.3 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, the
maximum rated discharge is 750 psig (51.7 barg) with standard pumps, and 1000 psig
(69 barg) with optional high-pressure construction on the downstream pump. With inlet pres-
sures greater than 200 psig (13.8 barg), optional high-pressure mechanical seals should be
used.
