4127C Series™ TEST

The 4127C Series™ internal gear stainless steel pump is the flexible, simple, and adaptable solution for a wide range of applications. This new generation of pumps comes standard with the U-Plus™ bracket for mechanical seals, as well as the ProPort™ casing that accommodates a variety of port sizes and types depending on your needs. It can handle flow rates up to 320 GPM (73 m³/h).

Features & Benefits

All stainless steel construction for corrosion resistance over a wider pH range
ProPort™ casing utilizes mounting pads on each port designed to fit a variety of different flange types and sizes, enabling flexibility when connecting pumps to piping
U-Plus™ bracket, available on H-QS sizes, offers seal location to be in the stuffing box or behind the rotor
Opposite porting on all pump sizes available

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.

Cooking Oils

Hot cooking oils are used primarily for deep fat frying of vegetables and meats. Some cooking oils or fats will become solid at room temperature, however the pumps are typically located close enough to the supply that it keeps the pump warm. The viscosity is typically water-thin at normal operating temperatures.
