IOM manual Tapflo Hose pumps

NOTE!
Even if all above safety instructions are met and complied with, there still exists a minor danger
in the event of a leakage or mechanical damage of the pump. In such case the pumped product
can emerge on sealing areas and connections.
1.10. Instruments
In order to ensure a proper control of the performance and the conditions of the installed
pump, we recommend using the following instruments:
- a pressure-vacuum gauge on the suction piping;
- a pressure gauge on the discharge piping.
The pressure intakes must be made of straight pieces of piping at a distance of minimum five
diameters from the pump inlets. The pressure gauge on discharge must always be fitted
between the pump and the regulation valve. The output can be read on the pressure gauge,
transformed into meters and then compared with the typical curves.
1.10.1. Electric power
The electric power absorbed by the motor can be measured by means of a wattmeter or an
amp gauge.
1.10.2. Optional instruments
The optional instruments can indicate if pump is working in an abnormal way. The abnormal
conditions can be caused by: accidentally closed valves, lack of pumped liquid, overloads, etc.
1.10.3. Thermometer
If the temperature of the pumped liquid is a critical parameter, provide the installation with a
thermometer (preferably on the suction side).
1.10.4. Pressure safety device
The pump cannot run against higher pressure than stated in this IOM manual. Therefore the
pump must be equipped with an appropriate pressure safety device such as a pressure switch,
bypass line with a pressure relief valve or motor overload protection that will automatically stop
the pump when pressure rises above allowable levels.
