Reliable pumping from versatile TopGear
pumps
When reliability is of paramount importance to your liquids handling application, regardless of your need to transfer either thin or thick liquids, the choice of pump is crucial
Understandably, the focus of pump users is not the pump itself, but more importantly, its ability to provide smooth, uninterrupted production and at a lower cost In these situations TopGear pumps, available from JP Pumps (a division of the SPX Process Equipment), provide the highest levels of reliability and long life with capacities from 0.5m3/h up to 125m3/h at pressures up to 20bar

Top marks for reliability from TopGear Pumps
When reliability is the priority for your process or manufacturing application, where you need to transfer both thin and thick liquids, the choice of pump is crucial
The range of pumps is divided into three main ranges; the L - range for low viscosity, high efficiency, the G - range for general purpose liquids transfer and the H - range for more demanding applications.
A key feature of TopGear pumps is the improved design of the integral gear section with an optimised teeth profile to ensure smooth and efficient flows for either free-flowing or highly viscous media.
The pump has a simple, yet effective operating principle, which starts with the rotor and idler un-meshing, creating an under-pressure with the liquid entering the newly created cavities.

When liquid transfers demand a compact, economic and space-saving pump, with a choice of suction and pressure connections, Combiflex vertical single-stage centrifugal pumps are the ideal solution
Robust self-priming pumps for optimum reliability
FreFlow self-priming centrifugal pumps are particularly suited to chemical and pharmaceutical applications which require safe and efficient transfer of low viscosity, contaminated liquids
Liquid is transported in sealed pockets to the discharge side of the pump.
The walls of the pump casing and the crescent create a seal that separates suction from the discharge side.
Finally, the rotor and idler mesh and liquid is pushed into the discharge line.
Other features and benefits of the TopGear H and G models include improved priming and low NPSHr with maximised ports and ports above the centreline, optimum efficiency with axial rotor locking, adjustable clearances and hydraulic design.
Less downtime and minimal maintenance is assured thanks to the front and back pull-out panels and the simple cartridge design, while long life is assured with the pumps compact rotor, strong shafts and maximised bearing design.
The L range offers high volumetric efficiency thanks to small radial and axial clearances ensuring reduced slip plus optimised rotor and gear shape.
Long service life is assured by large bearing diameters, rotors machined in one piece from steel bar and hardened interior parts while less downtime is achieved, with the pumps and motors flanged to pedestals providing correct alignment between the pump and drive shaft.
A range of options are offered which enable the pumps to meet specific application requirements.
For example; packed gland, single and double mechanical, lip and cartridge seals, heating and cooling jackets and single and double safety relief valves.
TopGear pumps are suitable for a wide range of applications including petrochemicals, chemicals, paint and ink, resins and adhesives, pulp and paper and also food processing.
