2. OPERATION
2.1
Health and safety
The pump must be installed according to local and national safety rules.
The pumps are constructed for particular applications. Do not use the pump on applications
different from that for which it was sold without consulting us to ascertain its suitability.
2.1.1
Protection
In the interest of health and safety it is essential to wear protective clothing and safety goggles
when operating, and/or working in the vicinity of Tapflo pumps.
2.1.2
Environments in danger of explosion
The standard stainless steel series pumps are not allowed to operate in environments in danger of
explosion. Static electricity may occur in the pump under operation, which may cause explosion
and injury. Special ATEX approved pumps are available for such applications. Consult Tapflo AB for
further information. Follow the explosion safety rules applicable at the location for the pump.
2.1.3
Air pressure
The maximum air pressure for Tapflo pumps is 8 bar. Higher air pressure than 8 bar can damage
the pump and may cause injury to personel in vicinity of the pump. If you intend to apply a higher air
pressure than 8 bar, please consult us.
2.1.4
Noise level
At tests, the noise level from a Tapflo pump has not exceeded 80 dB(A). Under some circumstances,
for example if the pump is operating under high air pressure at low discharge head, the noise can
be inconvenient or hazardous for personel staying for long periods in vicinity of the pump. This
hazard can be prevented by:
- using suitable ear protection
- lower the air pressure and/or raise the discharge head
- lead the outcomming air from the place by connecting a hose from the muffler connection of the
pump.
- use elastomer valve balls (EPDM, NBR or polyurethane) instead of PTFE, ceramic or stainless
steel, provided that the elastomer is compatible with the pumped liquid.
2.1.5
Temperature hazards
Raised temperature can cause damage on the pump and/or pipings and may also be hazardous
for personel in the vicinity of the pump/pipings. Avoid quick temperature changes and do not exceed
the maximum temperature specified when the pump was ordered. See also general max tempe-
ratures based on water in chapter 5 "Data".
2.2
Before starting the pump
-
Make sure the pump is installed accordning to the installation instruction (section 1).
-
Filling of the pump with liquid before start is not necessary.
-
When installation is new or reinstalled, a test run of the pump with water should be conducted to
make sure the pump operates normally and does not leak.
