The 4724 Series™ internal gear pump is the perfect solution for soaps & surfactants, acids & caustics, and more due to its stainless steel construction and jacketed bracket. It can handle flows up to 110 GPM (25 m³/h).
Features & Benefits
- Cast iron mounting bracket lowers overall pump cost (316SS wetted parts)
- Behind the rotor mechanical seal eliminates the shaft and bushing from being exposed to media
- Jacketed bracket provides the ability to maintain uniform temperature to sealing area

Soaps
Kettle soap, soap stock, soap skimmings, and liquid soap are a mixture of sodium salts of various fatty acids of natural oils and fats. Common soap is largely a mixture of the sodium salts of palmitic, stearic and oleic acids. Rosin soaps for laundry purposes are made by adding a soap made from rosin or rosin itself to an ordinary soap.

Acids / Bases
Extremes on the ends of the pH scale that can result in severe corrosion and chemical attack of the pump body, gears, bushings, and elastomers. Pump construction will ultimately be driven by the specific liquid being handled and the construction that offers the greatest chemical resistance.

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.
