Please note:

On TG MAG pumps the radial rotor clearance C1 is slightly larger than on other TopGear pump families, while clearance class C2 and C3 are identical with the standard range.

TG MAG 185-125	325	650	975

The extra clearances are realised as follows:

Rotor and Idler:	By extra machining of outside diameter (code 2, 3);
	or standard = 1
Pump cover:	By adjusting during assembly (code 0, 2 , 3);
	or standard = 1
Idler pin / bush bearing;	2 cases are possible: (standard = 1)
	*)	case 1: by providing a special pin (6 material) with
		adapted pin diameter (code 2 or 3)
	**)	case 2: by providing a special bronze bush with adapted
		inside bush diameter (code Y or Z).

If there are metal particles in the liquid, customer must install a magnetic filter before the liquid reaches the pump.

If there are hard particles in the liquid, consult your distributor.
