2.0TONKAFLO 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 m3/h) 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.

SS	2900 rpm	3500 rpm	Maximum
	50 Hertz	60 Hertz
Series	Minimum - Maximum	Minimum - Maximum	Efficiency
500	1 - 6 gpm	1.5 - 7 gpm	40%
	(0.23 - 1.4 m3/h)	(0.34 - 1.6 m3/h)
1000	3.3 - 11 gpm	4 - 13 gpm	49%
	(0.75 - 2.5 m3/h)	(0.91 - 30. m3/h)
1800	4 - 17.5 gpm	5 - 21 gpm	57%
	(0.91 - 4.0 m3/h)	(1.14 - 4.8 m3/h)

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