1.8.1. 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.
1.8.2. Electrical safety
Do not carry out any maintenance or/and operation on the pump while it is running or before
it has been disconnected from the power supply. Avoid any danger caused by electric power
(for details see current regulations in force). Check that electrical specifications on the data
plate are equivalent to the power supply to which it will be connected.
1.8.3. Chemical hazard
Whenever the pump is to be used for pumping a different liquid, it is essential to clean the
pump beforehand in order to avoid any possible reaction between the two products.
1.8.4. Noise level
Hose pumps, including the motor, in normal operating conditions produce a sound level below
70 dB(A). The major sources of noise are: liquid turbulence in the installation, cavitation or any
other abnormal operation that is independent from the pump construction nor the pump
manufacturer. The user must provide suitable protective means if the sources of noise could
produce a harmful noise level for operators and for the environment (in compliance with current
local regulations).
1.8.5. Temperature hazards
➢
Raised temperature can cause damage on the pump and/or piping and may also be
hazardous for personnel in the vicinity of the pump/piping. Avoid quick temperature
changes and do not exceed the maximum temperature specified when the pump was
ordered. See also general max temperatures based on water in chapter 5.
Data
➢
When the pump is exposed to ambient temperature variations or if there is big difference
between the temperature of the product and the surrounding, the tightening torques of the
housing nuts should be checked periodically as part of preventive maintenance (please
contact Tapflo for interval proposals). Ambient temperature limits are form -20
º
C to +40
º
C.
NOTE! If ambient temperature is below 0
º
C, add antifreeze to the lubricant inside the pump.
Remove 15% of the lubricant and fill with antifreeze to the appropriate level (see Fig. 3.7.5.).
➢
If a hot product is pumped, the pump should not stand still when filled for a longer period
of time. This could cause leakage from the pump.
➢
Below 0°C (32°F) plastic materials become more fragile what can cause accelerated wear of
parts made of these materials. This is a hazard that has to be accepted when pumping such
cold products. Also in such case, when a pump is not operational it should be drained of all
liquid.
➢
Bear in mind that the viscosity of the product changes with temperature. This has to be
taken into consideration when selecting the pump.
