CXR Series pumps are available in four sizes: CXR 10, CXR 20, CXR 50, and CXR 130. The manufacturers claim that the main benefit of the CXR pumps is their design flexibility, which allows them to be used for a number of different low- to medium-duty applications, such as a drum pump. All CXR models can be converted from ball to cylinder valves, and vice versa. Incorporating ball valves is aimed for liquids containing particles, while cylinder valves are can be used for transfer applications requiring suction lift.
Operational safety
In the CXR pump’s construction, housing parts are attached with housing bolts that are tightened against a diaphragm-sized ring located on each side of the pump. This method of construction allows the pump to transmit the forces of the housing bolts onto the housing parts evenly. This consistent flow of pumping forces and an ability to apply increased bolt torque result in an increase in the CXR pump’s operational safety.
Air-control system
The CXR pumps feature Almatec’s Perwing P air-control system which has no dead spots and does not need maintenance or lubrication. The CXR pumps are also self-priming and dry-run capable, with suction-lift capabilities that allow containers to be emptied to the very last drop, even without supervision. The CXR’s housing is made from solid-block PE conductive for good chemical resistance. Their design and construction also allows the CXR pumps to be operated in potentially explosive atmospheres and with flammable liquids, per ATEX-compliance standards.
