• The basic CR pump range, which applies to almost any industrial solution, is in itself the broadest range available. With our modular approach, we have made it even broader. The basic CR pump range is available as standard in three different materials including two grades of stainless steel, and all-titanium versions in eleven flow sizes, capable of producing up to 40 bars of pressure, and with a variety of shaft seals, rubbers, supply voltages and frequencies. These pump parts, typically vulnerable to difficult liquids or particularly demanding operating conditions, have been optimised to the task and designed for specific requirements. Impressive as the CR range is, Grundfos offers much more. A complete range of pump solutions means that all industrial and domestic water applications can benefit from the Grundfos touch. Applications include: ? Process water systems ? Washing in cleaning systems ? Sea water systems ? Pumping of acids and alkalis ? Ultra filtration systems ? Reverse osmosis systems ? Swimming baths These pump models have been designed for operation in either open or closed loop control arrangements. The Default control mode is “Uncontrolled Curve”. For closed loop control either differential pressure transducers, pressure transducers or temperature transducers can be supplied as separate items; as required. Pressure transducers are listed with their ranges in the following tables as the recommended option. We recommend that a pressure vessel is fitted on the discharge pipe close to the pressure sensor and a non-return valve should be fitted to the pump suction, on all CRE pumps where the “stop” function is activated. All Pumps are WRAS Approved and with Grundfos MGE Motor
