3.3 Revolution Range Operating Parameters.
The maximum pressure and speed operating parameters are given in Fig 6. In
practice these may be limited due to the nature of the product to be pumped
and/or design of the system in which the pump is to be installed. Consult Wright
Flow Technologies or your Wright Flow Technologies distributor for assistance.
The operating temperature limit of the pump is determined by the rotor clearance.
For the circumferential piston pumps (CPP):
• Size 6 and 7 - four rotor clearance bands:
(a) STANDARD CLEARANCES FOR 93°C / 200°F
(b) FRONT FACE CLEARANCE 105°C / 220°F
(c) HOT CLEARANCES FOR 150°C / 300°F
(d) CHOCOLATE CLEARANCE
(e) CLEARANCES FOR 93°C / 200°F (STAINLESS)
(f) FRONT FACE CLEARANCE 105°C / 225°F (STAINLESS)
(g) HOT CLEARANCES FOR 150°C / 300°F (STAINLESS)
(h) CHOCOLATE CLEARANCE (STAINLESS)
The pump should not be subjected to sudden temperature changes to avoid the
risk of damage from sudden expansion/contraction of components. Care should
be taken when selecting pumps for handling liquids containing abrasive particles
as these may cause wear of pump head components.
