Tuthill lubrication and circulation pumps handle many viscosities and sustain a constant flow at any pressure. With only two moving parts the internal gear design allows the pump to handle more viscosities than it's competitors.
Simple, Compact Design offers high efficiency and longer life.
Positive Reversing Action - The unique reversing feature allows the lubrication and circulation pumps the ability to reverse flow without the use of valves.

The High-Speed Compact internal gear pumps offer heavy-duty design and small footprint for rotating equipment lubrication such as compressors and turbines. They are just one of many options that Viking offers for lubrication pumps. Others include gearbox lube pumps that pump in one direction regardless of shaft rotation, pump kits for OEM lubrication applications, and a variety of internal gear, external gear and gerotor pumps suitable for lube oil and grease applications,
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.
Viking in-line gear reducers offer reduction ratios from 2.6:1 to 35.1:1, with the ability to handle loads up to 260 kW. Solid input shaft or close-coupled input side adapters for IEC or NEMA motors offer mounting versatility. A second series of offset gear reducers, with ratios from 2.24:1 to 7.95:1, allows rotation of the input shaft to match motor height for easy mounting, while maintaining output shaft height. They are capable of loads to 30 kW.
