Pedrollo CKR Self-Priming Liquid Ring Pump

Description

Pedrollo CKR Self-Priming Liquid Ring Pump

INSTALLATION & USE

Designed for pumping diesel/naphtha and clean water free from abrasive particles and non-corrosive liquids that do not harm the pump’s components.
Their specific operating mechanism makes them an excellent solution when a compact self-priming pump is required or when the flow of the liquid is irregular or mixed with air.

We always recommend getting pumps installed by a qualified plumber.
The pump should be installed in an enclosed environment or sheltered from inclement weather.
