Pump Piping Connections
The standard model Tonkaflo SS5500, SS8500, SS12500, SS23000 and SS24000 Series
Pumps have grooved ends as shown in Figure 3.5 (Installation of Discharge Screen) to
accept Victaulic-type couplings. The couplings with 1000 psi (69 bar) working
pressure rating are available as an accessory and include a Buna-N gasket (standard).
Other gasket materials such as Viton or ethylene propylene are available. Consult the
factory.
The coupling gasket should be thoroughly lubricated before installation. Silicone
grease is recommended. Petroleum grease is suitable for most gasket materials, but
is not suitable with ethylene propylene (EPDM).

Lubrication of Pump Bearings
The pump bearings are not lubricated at the factory.
The bearings are lubricated by maintaining a static oil level within the bearing frame.
One quart (0.95 L) of oil is provided with each new Tonkaflo oil lubricated pump.
Additional oil can be purchased from GE (Section 10.2, Standard Model Parts List).
A heavy-duty premium hydraulic and lubricating oil (anti-wear, non-detergent, rust,
oxidation, and foam inhibited) should be used, such as those listed in Table 3.3 (Typical
Heavy-Duty Hydraulic and Lubricating Oil Types).
Table 3.3
Typical Heavy-Duty Hydraulic
and Lubricating Oil Types
A #5 TRICO OILER is provided (not installed when shipped) and is used to maintain the
static oil level. The removable crossbar bottle support for the oiler was adjusted at the
factory to maintain proper oil level. If adjustment is lost, reset according to Figure 3.6
(Installation of Oiler). The crossbar support must be used. Do not discard.
