Pumps ideal for biodiesel production

Blackmer has announced that its NP and SNP Series sliding vane pumps are ideal for a wide array of applications required in biodiesel production and processing. Among these applications are the preparation of the clean/heat filter, mixing of alcohols and catalysts, combining methanol and caustics with oils, transesterification, separation of biodiesel and glycerin, recovery of methanol and glycerin, purification and in-line blending. The NP and SNP Series pumps are capable of meeting these demands because they offer the flexibility needed to handle clean, non-corrosive liquids at varying temperatures, pressures and viscosities. This allows them to be used in various loading/unloading and transfer applications, while the stainless-steel construction of the SNP model makes its ideal for handling a variety of corrosive or caustic fluids, which is a crucial consideration in the manufacture and shipping of biodiesel. NP Series pumps are available in five sizes, with port sizes from 1.5” to 4”. They feature flow rates from 5 to 500 gpm (19 to 1,893 lpm) at operating temperatures up to 500°F (260°C). They can handle viscosities ranging from 30 to 100,000 ssu (1 to 21,000 cSt) at differential pressures up to 200 psi (13.8 bar).
