TopGear MAG - Protecting your future
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 on process plants.
TopGear MAG provides environmental, human, legal and economical protection - |

| The Universal Mag Drive is the ideal sealing technology for critical liquid containment applications within Viking’s Universal Seal product line. It is dimensionally interchangeable with Viking's Heavy Duty bracketed and Universal Seal pumps, allowing for easy upgrade from packed or mechanical seals to sealless technology. The Universal Mag Drive’s hermetic, static sealed canister provides the highest level of liquid containment available by eliminating traditional dynamic shaft seals. It also eliminates housekeeping issues and downtime due to seal failure. This product is designed to handle a broad range of applications requiring continuous duty at pressures up to 200 PSI (14 Bar). |

| High economy, optimal efficiency and silent in operation. These are all important features which particularly characterize our transfer pumps. Compact design, low weight, solid construction and workmanship, anti-wear coatings, application-specific materials, sizes and seal variants, as well as numerous accessories and type of connections are additional reasons which make KRACHT transfer gear pumps more than interesting for every user. And this is our motto for every type of pump: only the best is good enough. |

| Lovejoy offers a variety of designs and models in its gear coupling family. From standard, off-the-shelf stock to new, high speed, special designs, Lovejoy can satisfy your gear coupling needs. The original Continuous Sleeve, or “C” coupling, offers a lightweight, compact, and simple design without compromising torque carrying capacity. The Flanged Sleeve, or “F” coupling, is available in exposed or shrouded bolt styles in which the number of bolts, size of bolts, and bolt circle are identical with industry standards. The nylon sleeve gear couplings, Nyflex and Mite, are compact, lightweight couplings that use a nylon sleeve and two sintered iron hubs. Lubrication is not required with the nylon sleeve. Lovejoy also has an All Metal Labyrinth Seal coupling and an Alloy Steel coupling. The All Metal Labyrinth Seal coupling is a flanged sleeve style, but uses no elastomeric seals. The Alloy Steel coupling is made from AISI 4140 steel. |

APPLICATION:
The type oil gear pump AD-L is ideally suited in single-line centralized lubrication systems. In these systems, lubricant is being delivered intermittently under pressure (pressurizing - and relief cycles) through the main feed lines towards the meter elements installed downflow and
from there through the lube lines to the points of application.
FUNCTION:
The oil lubricator basically consists of a gear pump with A.C. single-phase motor, the oil reservoir, the electronic control unit and a valve which ensures that the line is depressurized when the A.C. single-phase motor is switched off (relief cycle). An integral pressure relief valve is opened as soon as reaching a pressure of 2 MPa (20 bar) thus protecting the oil gear pump from damage in the event of an overpressure situation occuring. After relief the main line, the valve maintains a resudial pressure of approx. 0.08 MPa (0.8 bar) and thus prevents that the main line runs empty. The entire system is either time- or pulse controlled, at choice. |
