SPX has launched its Novados double-acting diaphragm pump to meet the specific needs of the oil and gas market. It was specifically designed for offshore applications in the oil and gas industry to reduce the footprint and weight of a pumping installation. Its single double-acting head provides the capacity of equivalent duplex pumps but its size and weight are typically reduced by about 20 percent.
The Novados metering pumps provide a precise injection of chemicals and can handle aggressive and harmful fluids safely. They use hermetic seals to provide virtually leak-free operation while delivering the advantages and accuracy of reciprocating plunger pump technology.
This increases efficiency and offers a high safety performance in applications that use aggressive or harmful fluids. The pump is ideal for applications such as methanol or glycol injection as well as for handling a wide range of fluids including liquid carbon-dioxide, liquid ammonia, hydrocarbon condensate, LPG, toluene and water. The main benefit of this pump head technology is to provide the equivalent pumping capacity of a duplex pump with just a single pump head and gear – significantly reducing the size and weight of an installation.
A patented positive diaphragm position control system (PDPC) which does not obstruct the pumping chamber makes the pump suitable for the metering of slurries and higher viscosity fluids. This also helps prevent the diaphragm from being damaged under emergency conditions such as a blocked pipe or closed valves upstream or downstream of the pump. The pumps use double diaphragm protection with TFE diaphragm material as standard and are also available with a rupture alarm if required. They also have an inbuilt control device and do not require a variable speed drive or control valve, making installation straightforward.
