Refined Fuels
Refined Fuels Refined fuels would include petroleum based fuel oils and some Jet Fuels. Their viscosity and temperature handled can vary greatly. Normally these are handled in bulk transfer operations.
Reclaimed Asphalt
Reclaimed Asphalt Reclaimed Asphalt is typically a dirty or filled asphalt containing a bitumen blend with solids that could be limestone or rubber based. These solids result in very high viscosities and abrasive nature, resulting in the need for extra clearances, low run speeds, and the inclusion of hardened parts.
Polyvinyl Acetate (PVAC)
Polyvinyl Acetate (PVAC) Poly Vinyl Acetate, or PVAC, is a colorless, odorless, tasteless, non-toxic, transparent, thermoplastic solid. It is used in latex water paints, in hot melt and other types of adhesives, for coating and finishing fabrics, as a component of lacquers, inks and in caulking compounds and chewing gum. PVAC is insoluble in water,…
Polyurethanes
Polyurethanes Polyurethane foam is produced when a polyether is treated with a isocyanate in the presence of water and a catalyst, as well as fillers, dispersing and emulsifying agents, etc. The water reacts with the isocyanate group to cause cross linking and curing, and also produces carbon dioxide which causes foaming. If the polyurethane has…
Polyol
Polyol Alcohols having many hydroxyl radicals are called polyols. Many companies market polyols under their own trade names. Product viscosity varies greatly depending on the specific polyol, but can be as thick as 40,000 cP. Polyols are often blended with isocyanates, so pumps handing polyols are often requested to be built using isocyanate compatible lubricants.
Peanut Butter
Peanut Butter Peanut butter is made from mixing ground up peanuts with various additives and fillers. From the mixer, peanut butter is pumped through a deaerator and/or heat exchanger to remove entrained air and drop the temperature prior to being pumped to the jar filling machines.
Paints
Paints Paints are shear sensitive liquids that can have a variety of solvents & pigment load concentrations that bring with them abrasive wear and chemical compatibility concerns.
Molten Sulfur
Molten Sulfur Molten Sulfur is a difficult to pump liquid due to the very narrow temperature range that it can be handled. Molten Sulfur is typically solid up to 240°F, and then re-solidifies again around 370°F. The suggested handling range is 270°F – 310°F, where the viscosity is 6 – 9 cP. The pump needs…
Molasses
Molasses Molasses is defined as the syrupy mother liquor left after sucrose has been removed from the cane juice by concentration. If only one crop of crystals had been removed, it is called First Molasses. If the second crop has been removed, the product is termed Second Molasses, and so on. When no more cane…
Massecuite
Massecuite Massecuite is the mixture of raw sugar crystals and molasses, made by seeding supersaturated cane or beet juice, prior to the removal of the molasses by centrifuging. It contains a high concentration of abrasive sugar crystals.
