Internal Gear pumps

Gear pumps are used in all types of manufacturing industries for the transportation of both thin and thick liquids, from chocolate to diesel fuel. Our gear pumps have a sturdy design, offering high reliability as well as long life.

Johnson Pump's gear pump design is based on an internal idler gear rotating inside of a larger rotor. Internal gear pumps are robust, give an even flow, handle both low and high viscosity products, are capable of high pressure and are self-priming.

TopGear H Internal Gear pump

TopGear H-series is available in nine different sizes. The modular design gives a wide range of possibilities. Shaft seal options include single and double mechanical seals as well as packed gland and cartridge seals. Baseplate-mounted.Heating and cooling jackets are available for pump cover and around shaft seal. Single or double safety relief valves are available built-on. Connections from 32 to 150 mm.

Product Type:

API, Nodular, Stainless steel

TG H-range is for high demanding application

TopGear L Internal Gear Pump

TopGear L-series is available in six different sizes. Shaft seal options include mechanical seals, packed gland and double flushed PTFE lipseals. Flange-mounted or bracket for foot-mounting, the TG L pedestal fits IEC-flanged motors. Safety relief valves are available built-on or separately. Connection sizes from 1" to 1.1/2".

Product Type:

Low Flow

The TG L-range, for low viscosity, high volumetric efficiency

TopGear MAG internal gear pump

TopGear MAG is a range of leak-proof internal gear pumps for low and high viscous liquids which are corrosive, toxic, aggressive or expensive. Total containment of the liquid inside the pump is achieved using a hermetically sealed can, which isolates the liquid from the surrounding environment. This eliminates the need for shaft seals and the associated wear and leakage that would normally be experienced.

The Magnetic Drive pumps are therefore not only environmentally friendly they also contribute to improved safety in chemical and process plant environments.

Complying amongst others with the “ATEX” (ATmospheres EXplosibles) directive, magnetic drive pumps make an important contribution to health and safety of process plants.
