The 8127A Series™ internal gear pump is the perfect solution for petrochemicals, isocyanates, polyols, and more due to the sealless mag drive which keeps hazardous liquids contained. It can handle flows up to 500 GPM (114 m³/h).
Features & Benefits
- Sealless mag drive eliminates the shaft seal to provide the highest level of liquid and vapor containment
- All liquid and vapor is hermetically sealed in the pump
- Used especially for hazardous and difficult-to-seal liquids

Also known as TDI, MDI, or diisocyanate. Isocyanate is used as a hardening or curing agent in polyurethane foams, industrial coatings, elastomers, inks, and resins. It is extremely sensitive to moisture in the air and hydrocarbons making air-tight seal options extremely critical.
- Ductile iron
- Sealless design
- Bearing option for compatibility
- Higher pressure capability
- Capacities to 190 GPM
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.
- Cast iron
- Cartridge lip seal sealing options
- Bushing options for compatibility
- Capacities to 500 GPM
Resins are high viscosity liquids with potentially shear sensitive (thinning) components, and made up of solvents, waxes, surfactants, and semi-solid resin particles all with various chemical compatibility concerns. These resins can be used in polyurethanes, epoxies and other adhesives. In some cases, resins contain pigments that bring with them abrasive wear concerns.
- Cast iron
- Abrasive resistant sealing option
- Hardened iron bushings and hardened steel shaft
- Low shear
- Capacities to 400 GPM
Adhesives are a group of substances, such as cement, glue, mucilage, and paste that are capable of holding materials together by surface attachment. Adhesives are made from many different basic materials, among them dextrin, latex, silicones, liquid rubber, resin, sodium silicate, and starch.
Caustic (Sodium Hydroxide)
Sodium hydroxide is soluble in water, alcohol and glycerol. It is used in the manufacture of other chemicals, rayon and film, petroleum refining, pulp and paper, making of aluminum, refining vegetable oil, in detergents, soaps, textile processing, in reclaiming rubber and as an alkali in foods. The viscosity ranges from water-thin to 40 cP depending on concentration and temperature.
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.
- 316 Stainless steel
- High viscosity and abrasive resistant sealing options
- Capacities to 110 GPM
The wide range of viscosity of various solvents plays a key role in determining the best pump for handling the application. Pump construction will ultimately be driven by the specific liquid being handled and the construction that offers the greatest chemical resistance and is the most viscosity appropriate.
Various liquids designed to enhance or change the properties of the bulk liquid such as fuels, greases, and oils. These additive liquids include antioxidants, rust inhibitors, anti-wear agents and viscosity modifiers.
Biofuels include Biodiesel and Ethanol. These are fuels made from renewable resources and typically blended with refined fuels as additives.
