Pax tankless systems can be utilized with central lubrication supply systems or to spray lubrication directly out of the drum or other customer-supplied reservoirs. Depending on the application, the tankless units can be provided with the optional diaphragm supply pump and one of the optional filter assemblies listed on the following page; or the units can be supplied without a pump or filter assembly for central lubrication systems.

Model V5M

The Pax Model V5M may be utilized for central lube system applications. This assembly includes 5 solenoid valves that can be independently controlled and may be programmed to spray at different intervals and for different durations during a press cycle. Either Pax’s control or a customer-supplied control can be utilized to control the individual solenoids on this unit.

Power Cord and Plug

For the standard 115 V system, a nine-foot power cord with a three-prong plug can be provided.

Air Agitation

For use with water-soluble lubricants to assure the lubricating medium remains in suspension. A needle valve regulates the amount of air applied to the lubricant reservoir.

Low-Level Float

The float switch is designed to connect to the press’ top stop circuit to prevent running the dies dry.

Automatic Refill System:

This system consists of three separate components, listed below, that work in conjunction to maintain fluid in the reservoir.

Automatic Refill Solenoid Valve

This valve mounts on the rear of the lube system reservoir and is controlled by the float switches to maintain an adequate supply of lubricant to the system. The valve has a 3/8” NPT (female thread) to which the customer needs to connect their pressurized, lubricant supply. Note: A constant, pressurized lubricant supply must be provided to the valve.

Automatic Refill Floats

A dual float switch system that works in conjunction with the auto refill solenoid valve. These switches open the valve when the fluid is at a level where it needs to be refilled and they close the valve when the reservoir is full.

Low Level Float

This additional float switch detects if the lubrication level in the reservoir goes significantly below the refill level. By interfacing this with the press’s top stop circuit, the customer can stop the press before the reservoir runs out of fluid.

Reservoir Strainer For 5-gallon, 15-gallon & 30 Gallon Systems

This strainer adapts to the lube system reservoir to prevent larger particles from entering the reservoir when fluid is poured into the system. Note: Fluid that enters the system via the return line does not pass through this strainer.

Pressure Monitoring Sensors for Spray Lines, (PN 05-1444-30):

This Sensor Assembly is an electronic pressure monitor that allows for the monitoring of a specific spray line of your lubrication system via die protection or PLC integration.

By monitoring the changes in pressure during each spray cycle, the sensor can determine if that line is spraying each cycle. During a spray cycle, the pressure in the spray line rises quickly as fluid is dispensed through the nozzle. After a point in time, the pressure in the spray line reaches a maximum and begins and drops again. When set correctly, the set point pressure of this sensor is triggered when the pressure initially rises during a spray cycle, and the reset point pressure on this sensor is triggered when the pressure decreases. The change of output provided by the sensor as a result of these pressure changes can then be monitored by the customer.

The pressure settings for the switching output of the sensor are controlled via the set and reset point, which is manually set by the user utilizing the orange dials on the sensor. Each Pax spray nozzle has a unique line pressure that is maintained between sprays. The pressure switch must have the set point and reset point above this baseline pressure. Values for the set point, reset point and baseline pressure are subject to each customer’s particular application, cycle speed, and hardware configuration. The switch is capable of monitoring the Pax standard nozzles, high-pressure nozzles, and piston nozzles assemblies. The high-pressure piston requires a higher pressure range and is not suited to this sensor.

The pressure switch utilized is a PNP-type sensor that requires a 24 VDC power supply and it provides both normally open and normally closed outputs. Note: It is the customer’s responsibility to provide power to each sensor and to integrate the sensor outputs with either their die protection system or with a PLC as required. Pax will supply a 5-meter long, M12, 4-pin connector cable with each sensor for the customer to utilize for this integration.

Spray Tips (contact Pax for additional tip options)

Note: A low-viscosity (Tellus #10) lubricant was used to obtain the pattern sizes described. The tips were placed in the vertical position and held 6″ from the surface with an air pressure setting on the FRL of 35 psi. Pattern sizes may vary depending on lubricant viscosity and air pressure setting.
