Design wktr

Vertical can-type ring-section pump. Type VS6 to API 610 and DIN ISO 13709, multistage, first-stage impeller designed as suction impeller, radial impellers. ATEX-compliant version available.

Application pump wktr

Pumping condensate and other NPSH-critical products in industrial plants, particularly in refineries and petrochemical plants.

Applications pump wktr

WKTR pumps can be used for Hydrocarbons for refinery and petrochemical applications, as well as for Ammonia, condensate handling where NPSHA is critical

Desing Details pump wktr


Vertical, radially split, ring section pump with radial single entry impellers, multistage. The stages are sealed off against each other by O-rings & clamped together by tie rods.
Provision is made on Can to mount complete pump on separate mounting plate for better structural stability.
The suction and discharge nozzles are always horizontal and inline.
WKB : Without Can execution, available on request.
