D : peripheral diameter of rotor (outside diameter)

Vs-100 : displaced volume pro 100 revolutions

n.max

: maximum allowable shaft speed in rpm

n.mot

: normal speed of direct drive electric motor (at 50Hz frequency)

Q.th

: theoretical capacity without slip at differential pressure = 0 bar

v.u

: peripheral velocity of rotor

v.i

: velocity of liquid in the ports at Qth (inlet and outlet port)

∆p

: maximum working pressure = differential pressure

p test

: hydrostatic test pressure

Maximum viscosity

Maximum viscosity = 10 000 mPas

Remark:

Figures are for Newtonian liquids at operating temperature

3.6Pressure

For performance on pressure three kinds of pressures must be considered i.e.

Differential pressure or working pressure (p) is the pressure on which the pump normally operates. The maximum differential pressure of all TopGear MAG pumps is 16 bar.

Maximum allowable working pressure or design pressure (p.m.) is the pressure on which the pump casing is designed. It represents the maximum allowable pressure difference between internal pressure in the pump casing and the atmosphere. On TopGear MAG pumps the design is 16 bar for cast iron pump casings and 20 bar for stainless steel pump casings

Hydrostatic test pressure is the pressure on which the pump casing including separation can of the magnetic coupling is tested. For TopGear MAG pumps the hydrostatic test pressure is 24 bar.

3.7Sound level

3.7.1Sound level of a pump without drive

Sound pressure level (LpA)

The following table gives an overview of the A-weighted sound pressure level, LpA emitted by a pump without drive, measured according to ISO3744 and expressed in decibels dB(A). The reference sound pressure is 20µPa.
