Product features

The TopGear (TG) series combines robust construction with small or large clearances and a unique tooth profile on the active gear. TG GP series pumps are packing-sealed internal gear pumps. Their main advantages are the combination of robust construction, flexibility in clearance selection, unique inter-tooth space shape, and a wide range of material designs and additional options, such as a heating jacket, relief valves, or electric heating.

TG GP series pumps are characterized by a simple operating principle in which the liquid flows through the pump evenly with minimal pulsation. These pumps can also have a reversed flow direction. Most TG G series models are designed to operate at the normal rotational speed of a 50 Hz electric motor, allowing for direct drive.

Pumps in this series are used for pumping high-volume media in general applications. They handle medium or high viscosity media and high-temperature liquids perfectly. TopGear series pumps are self-priming and are used in many industries, such as food, chemical, paint, paper, and construction.

High efficiency – the design of this pump series features axial rotor locking, adjustable clearances, and a balanced hydraulic design. The TG GP series is characterized by high permissible torque and a single clearance class, enabling very good overall efficiency.
10 sizes – a range of models with a maximum capacity of up to 130 m³/h and a pressure of 16 bar, allowing the pump to be adapted to specific customer requirements.
Better priming – oversized ports for better performance, located above the pump centerline. This translates to lower required NPSH (Net Positive Suction Head).
Designed for medium or high viscosity media – undisturbed flow thanks to the optimized tooth profile on the active gear.
No leaks caused by thermal expansion – reliable sealing and pinion shaft with cover.
Well-thought-out design – based on two ball bearings with adjustable axial clearance. Pumps in this series can withstand higher permissible axial forces.
Easy maintenance – possibility of disassembly and access to the pump from both the front and the rear. Simple design and shorter service downtime.
Multiple material options – various designs of bearings and hydraulic parts are available.
Extended service life – compact rotor, robust shafts, optimal bearing design, option of hard metal bearings, vented seal area thanks to a bleed channel.
Various connection options – compliant with EN or ANSI.
Explosion-proof design – compliant with ATEX Directive, category II 2G.

Operation principle

Operating principle of SPX Johnson TopGear gear pumps

The rotor and pinion mesh together as they rotate. This creates sealed chambers with variable volume, resulting in a vacuum that forces the medium to flow into these spaces. The liquid is transported in the chambers from the suction side to the discharge side. The spaces are separated by an element that prevents the liquid from returning to the suction side. The medium is pumped to the discharge side as a result of the decreasing volume of the inter-tooth spaces.

Modular design

	Pump housing with integrated feet and line connections The pump housing can remain installed in the piping system during inspection and repair of the rotors and shaft seal.
	Front access module The entire front (gear, cover, and gear stub) can be removed for easy internal inspection and repair.
	Rear access module The rotor with shaft, intermediate housing with rotor bearing, shaft seal, and bearing bracket can be removed for easy inspection, repair, and shaft seal replacement.
	Top-mounted relief valve The pre-assembled and pre-set overpressure relief valve can be removed for inspection, repair, and if the direction of rotation or pressure needs to be changed.

Operation principle of relief valves

The relief valves used in the TGGP series are spring-loaded valves that open rapidly when the operating pressure rises to the set pressure value, which is pre-set by the spring. These valves limit the pressure difference (∆p) (or working pressure) between the suction and discharge, not the maximum pressure in the system. If the liquid cannot escape when the discharge side of the pump is blocked, overpressure can cause serious damage to the pump. The relief valve provides an escape route, directing the media back to the suction side after a certain pressure level is reached. An open relief valve signals that the system is not working properly.

Unloading drums filled with highly viscous liquids has never been easier. Our High Viscosity System (HVS) is designed to simplify this task, offering automated efficiency and exceptional product-saving capabilities. With HVS, you’ll experience a smooth unloading process, allowing you to focus on other critical tasks while achieving up to a 99% product removal rate. Say hello to effortless drum unloading with HVS.

Simplify the unloading of highly viscous liquids with our High Viscosity System Quattro-type (HVS Quattro). It is designed for high-volume applications where multiple drums (typically four) are stored on pallets. The HVS Quattro allows you to switch between the drums easily, thanks to our revolutionary articulated arm. Experience an impressive product removal rate of up to 99% which will reduce your production costs.

Unloading drums containing highly viscous liquids has become more efficient and precise with our High Viscosity System Flexi-type (HVS Flexi). This system simplifies the task, providing automation and effective product-saving features. The HVS Flexi ensures a smooth unloading experience, allowing you to concentrate on other important tasks while achieving an impressive product removal rate of up to 99%. It is suitable for applications with low to moderate volumes, such as supplying filling or packing lines directly.

Experience efficient and safe tank emptying operations with our flexible Unloading System. Designed to handle IBCs (Intermediate Bulk Containers), Mauser, Goodpack or Bag-in-Box® containers, totes, drums, barrels, and various other storage vessels, this system efficiently manages both low and high-viscosity products across a wide range of industries. Using a reliable suction lance mechanism, its innovative design and customizable control system ensure optimal performance while maintaining the highest industrial safety standards.

SLES* is an organic chemical compound with excellent cleaning and foaming properties. For this reason, it is commonly used in the production of cleaning agents, soaps, shampoos, and household chemicals. SLES is typically supplied to manufacturers of these liquids at a 70% concentration, and due to its physical properties, such a concentrated solution is difficult to process and must be diluted below 27% before being used in the production line. Our system enables continuous dilution with maximum efficiency and safety, reducing costs for the company in the long term.

Achieving precise mixing of ingredients to obtain the desired final product—while maintaining strict proportions, accuracy, and sequence—poses a major challenge for industrial manufacturers. The mixer was created specifically for this purpose. It is based on a system for diluting concentrated ingredients such as SLES. However, it has been designed in a modular way, allowing us to easily configure the system to meet actual production needs. The ingredients of the final product can be drawn from various types of tanks.

Precise and repeatable filling operations with our versatile container filler. Designed for applications requiring high accuracy and compatibility with various containers and products, from small-volume containers to large industrial drums. Filling accuracy below 0.1% ensures optimal production line performance while maintaining the highest industrial and sanitary standards. Suitable for both high- and low-viscosity products.

Responding to the individual needs of users, Tapflo offers the delivery of compact, automated process systems on a “turnkey” basis. Every demand for a non-standard pumping system is an opportunity for us to create a unique, tailor-made SKID system. Thanks to our extensive design and manufacturing capabilities, we provide solutions developed with specific functionality in mind. We offer virtually unlimited possibilities for the development of pumping units, both in terms of mechanics and automation.

Tapflo presents a series of chemical unloading systems designed for every branch of industry where liquids need to be stored, transferred, and dosed. Our solution, based on the use of a diaphragm pump, is suitable for handling viscous liquids, chemically aggressive substances, as well as those containing solid particles.

Several tank sizes can be combined with pumps in various configurations. Additional options allow the system to be tailored to specific needs. In this way, we have created the simplest and most versatile pumping solutions on the market.

saThe use of protection systems ensures not only efficient but also safe operation of diaphragm, lobe, gear, screw, and centrifugal pumps. Protection systems detect hazardous situations and respond immediately, for example by automatically shutting down the device. The pump protection solutions offered by Tapflo operate based on dedicated sensors. These include media presence sensors such as optical indicators, as well as tuning fork and capacitive sensors designed to detect the presence of a medium or to monitor its level in tanks or pipelines.

Tapflo presents a series of hygienic covers designed specifically for diaphragm pump users. The stainless steel housing is durable and sealed, effectively isolating the pump from its surroundings. Filled with a dedicated insulation mat, the hygienic covers are an ideal solution for acoustic or thermal separation of the pump. Tapflo industrial covers combine user-friendly design with high-quality materials. Built to last, they will serve reliably for years in nearly any application.
