3.2.1Self-priming operation

TopGear pumps are self-priming when sufficient liquid is present in the pump to fill up the clearances and the dead spaces between the teeth. (For self-priming operation see also section

3.18.5.2 Piping).

3.2.2Safety relief valve – Working principle

The positive displacement principle requires the installation of a safety relief valve

protecting the pump against overpressure. It can be installed on the pump or in the installation. (See 3.19.4 Checklist – Initial start-up – Safety relief valve)

This safety relief valve limits the differential pressure (∆p) between suction and discharge, not the maximum pressure within the installation.

For example, as media cannot escape when the discharge side of the pump is obstructed, an over-pressure may cause severe damage to the pump. The safety relief valve provides an escape path, rerouting the media back to the suction side when reaching a specified pressure level.

•The safety relief valve protects the pump against over-pressure only in one flow direction.

•An open safety relief valve indicates that the installation is not functioning properly. The pump must be shut down at once. Find and solve the problem before restarting the pump.

•When the safety relief valve is not installed on the pump, other protections against overpressure must be provided.

•Note! Do not use the safety relief valve as a flow regulator. The liquid will ciculate only through the pump and will heat up quickly.

Contact your distributor if a flow regulator is required.

3.3Sound

TopGear pumps are rotary displacement pumps. Because of the contact between internal parts (ro- tor/idler), pressure variations etc. they produce more noise than for example centrifugal pumps. Also the sound coming from drive and installation must be taken into consideration.

As the sound level at the operating area may exceed 85 dB(A), ear protection must be worn. See also section 3.7 Sound level.

3.4General performance

Important!

The pump is calculated for the liquid transport as described in the quotation. Contact your distributor if one or several application parameters change.

Liquids not suitable for the pump can cause damage to the pump unit and imply risk of personal injury.

Correct application requires that consideration be given to all of the following:

Product name, concentration and density. Product viscosity, product particles (size, hardness, concentration, shape), product purity, product temperature, inlet and outlet pressure, RPM, etc.
