Tornado Rubber Pump Mount Bracket 19555

The Rubber Pump Mount Bracket 19555 is the genuine OEM vibration isolator that carries the solution pump on the PS Series professional spotters. It is a bonded rubber-to-metal mount, and the machine uses two of them under the pump. It also fits the Tornado PS8226 Spotter 98226, the 230-volt build of the deluxe PS Series spotter.

What the Rubber Pump Mount Bracket does

A diaphragm pump does not run smoothly — it pulses, once per stroke, several times a second, for as long as the trigger is held. Bolted hard to the chassis, that pulse travels into the housing and turns the whole machine into a soundboard. These two mounts sit between the pump feet and the frame so the rubber takes the stroke and the chassis does not.

The isolation is doing more than keeping the machine quiet. Vibration transmitted into a sheet-metal chassis works fasteners loose, fatigues solder joints at the switch and the filter, and chafes wiring and hose where they pass a bracket edge. A pump sitting on dead mounts is a slow source of unrelated-looking faults elsewhere in the machine.

When to replace the pump mounts

Rubber mounts fail by hardening, cracking and collapsing rather than by breaking cleanly, so they are easy to overlook. Replace them when the rubber has gone hard and glossy, when it is crazed or split at the bond line, when the mount has taken a permanent set so the pump sits lower on one side, or when the rubber has separated from its metal insert and the pump can be rocked by hand.

The symptom customers notice first is not the mount — it is a machine that has become noticeably louder and buzzier in the last few months, with no change in how it cleans. A pump that was quiet and is now harsh is almost always sitting on tired mounts.

Heat and chemistry both shorten their life. A machine stored with solution left in the lines, or one worked hard in a warm vehicle bay, ages its mounts faster than the hours alone would suggest.

Fitting notes

Replace both mounts together — a new mount beside a collapsed one tilts the pump and loads the fittings on its inlet and outlet. Support the pump while the fasteners are out rather than letting it hang on its hoses, which is how a fitting gets cracked during an otherwise simple job. Tighten the fasteners until the pump is held firmly but the rubber is not crushed; over-torquing a rubber mount compresses it solid and removes the isolation you fitted it for. With the pump back in, run it against a closed trigger and listen — a correctly mounted pump is a muffled thrum, not a rattle.

Frequently Asked Questions

What does the Rubber Pump Mount Bracket 19555 do?

It isolates the solution pump from the chassis. A diaphragm pump pulses once per stroke, several times a second, and these bonded rubber mounts absorb that pulse so it does not pass into the housing, loosen fasteners or fatigue wiring and solder joints elsewhere in the machine.

How do I know if my pump mounts need replacing?

Look for rubber that has gone hard and glossy, crazing or splits at the bond line, a mount that has taken a permanent set so the pump sits lower on one side, or rubber that has separated from its metal insert so the pump rocks by hand. The usual first complaint is a machine that has simply become louder and buzzier without cleaning any differently.

How many mounts does the pump use?

Two, and they should be replaced together. A new mount beside a collapsed one tilts the pump and puts a side load on the fittings at its inlet and outlet.
