CPXV pump is a modular designed centrifugal pump that can be built to achieve almost all chemical liquid pumping requirements.The pump casing is designed for operation when submerged in the sump liquid. It is from the ASME B73.1 hydraulics series with inch studs.
A. Pump casing
The pump casing is designed for operation when submerged in the sump liquid. It is from the ASME B73.1 hydraulics series with inch studs.High chrome iron casing has a much reduced pressure rating of 12.6 bar (183 psi).This option is on high chrome iron/tungsten carbide coated casings.
B. Impeller
Depending on the wet end hydraulic, the impeller is either reverse vane or open. (High Chrome iron is only open.)
Drive size: 3K = Group 3, 2K = Group 2, 1K = Group 1.
C. Shaft
The shaft has a keyed drive coupling. It is supported by rolling bearing(s) above the sole plate and journal bearing(s) below.
D. Bearing housing
The bearing housing enables adjustment of impeller face clearance on the impeller via the bearing carrier jacking screws. High temperature pumps have a cooling fan above the pump thrust bearing housing and a heat sink disk fan below the pump thrust bearing but above the sole plate shaft seal.
E. Pump bearings and lubrication
The pump is fitted with a thrust type ball bearing that may be configured differently dependent on use.The thrust bearing(s) may be grease or oil lubricated depending upon the application.The journal (line) bearings may be lubricated by product or from an external source depending upon the application.
F. Sole plate shaft seal
The modular design enables one of a number of sealing options to be fitted. The option of a rigid coupling below the thrust bearing and above a mechanical seal provides back-pull-out servicing of the mechanical seal; removing the motor extends the back-pull-out feature to the thrust bearing.
G. Driver
The pump is normally driven by a flange mounted electric motor. An air or hydraulic motor may be utilized.The position of the terminal box can be changed by rotating the complete motor. To do this, remove the fasteners from the motor flange, rotate the motor and re-fit the fasteners.
H. Accessories
Accessories may be fitted when specified by the customer.
OPERATING LIMITS
Maximum pump ambient temperature: +55 ºC (131 ºF) where driver is also rated for this ambient.
Maximum pump speed: refer to the nameplate.
