Advanced diaphragm pump company LEWA has added two new model sizes to its range of micro-metering pumps to offer a wider choice of flow and pressure combinations, enabling more effective and cost- efficient gas odorisation.
The new pumps have been developed in response to increasing market demand for smaller units that address a wider range of flow rates and operating pressures.
Odorisation involves adding a strongly smelling chemical to otherwise odourless gases and is an essential safety requirement in many industries and gas distribution grids. Micro-metering pumps are key to the odorisation process.
They are used to add an intense odorant to flammable gases, such as natural gas, liquified petroleum gas (LPG), compressed natural gas (CNG), liquefied natural gas (LNG), and biogas, as they are being fed into a gas distribution network or trucks, railway tank cars or LPG and LNG vessels.
Walter Richter, head of sales odorisation & gas distribution at LEWA, explained: “Efficient odorization involves very precise dosing with minute quantities of chemicals, so selecting a pump to match the application’s flow rate and discharge pressure is critical to success.
“Traditionally, operators found that a pump suitable for the required flow rate did not deliver enough pressure, and vice versa.
“This leads to increased odorization costs due to pump oversizing and can cause poor injection accuracy. By introducing the MAH4 and MBH6 micro-metering pumps with new piston sizes, we can offer a wider selection of flow and pressure combinations, enabling more effective and cost-efficient odorisation with higher accuracy.”
