Transfer gear pump KRACHT
97 - 1056 cm3/r

Pump series BT and BTH are low speed gear pumps for
transfering medium and high viscosity fluids, provided they
have certain minimum amount of lubricating property, do
not contain any solids and are chemically compatable with
the materials of construction.
The standard material of construction for housing, bearing
cover and stuffing box cover is grey cast iron. The shafts
and gears are manufactured from case hardening steel, hardened
and ground. The shafts are carried in plain bearings
manufactured in bronze, with an option of sintered iron.
The rotary shaft seal is a packed gland consisting of PTFE
fillied Aramid yarn, and the static sealing between mating
parts is by means of either, liquid sealant or gaskets. All
sealing materials are asbestos free.
External axial loads are not permissable, restricted radial
loads can be absorbed, dependant on their magnetude and
direction.
Driving by flexible shaft coupling is preferred.
In the case of fluids which require elevated temperatures to
flow i. e. bitumen, wax etc. the BTH series pump should be
used. In this model the housing is double walled to provide
a heating jacked. The pump transfer chamber is heated by
circulating heat transfer fluid or steam through the jacket.
