Pre-Pressurized System

Pax is a pioneer of in-die lubrication. The original Pax system was designed and manufactured in 1975 by skilled tool and die craftsmen and tested in our own stamping facility.

By applying only the lubricant needed, only where it is needed, exactly when it is needed, Pax customers have:

Increased Production Speeds
Decreased Lube Consumption
Increased Die Life
Improved Part Quality
Improved Working Conditions

All Standard Pax Spray Systems are designed with the following Features:

“Airless” Spray, which provides better adhesion to the material and less airborne lube than sprays that mix air with the lubricant to better adhere to stock material
Ability to re-fill system while it’s in operation
Arranged to promote lubrication recycling
No Priming Issues
Customized configurations

System Overview

How It Works:

Pre-Pressurized Lubrication Systems utilize a diaphragm pump to provide a consistent supply of pressurized lubricant to each of its distribution pumps. The distribution pumps utilize air-driven pistons with a 10:1 air pressure to lubrication pressure ratio. Each time the distribution pumps cycle, a specific volume of fluid, (based on the volume setting of each pump), is pressurized at the 10:1 ratio and is sprayed onto the die or stock material. The air used to drive the distribution pump is not mixed with the lubricant. A separate distribution pump is utilized to supply lubricant to each individual spray line. This one-to-one arrangement provides the ability for individual volume adjustment and it assures that each nozzle provides an exact amount of lubricant with every spray. The volume of lubricant sprayed by each standard Pax distribution pump can be adjusted between 0.0023 and 0.0210 fluid ounces per spray (0.068 to 0.621 cc) and optional, high-volume distribution pumps are also available.

Ability to Spray Thin and Thick Lubricants:

The 10:1 ratio between the supplied air pressure and the resulting lubrication pressure enables this system to spray both low and high-viscous lubricants.

Note: When the viscosity of the fluid to be sprayed is above 300 SUS, it is important to notify and consult with Pax to assure that the system, the spray nozzles, and the spray lines are correctly configured.

Standard Control:

The Pax Pre-Pressurized system utilizes a PCB membrane switch. The standard functions of this switch include a hand cycle button to manually cycle the unit (this button is in the lower right-hand corner of the keypad) and a low-level indicator light, which will only be active if the unit is equipped with a low-level float, (this indicator is in the upper, left-hand corner of the keypad). Additional functionality is available with the optional advanced control.

This system is arranged for:

A contact closure, (dry contact), is required to automatically cycle the system.
Input Power of 115 VAC 60HZ supply OR 24VDC.

Dual Solenoid & Dual Lube Systems

Dual Solenoid Systems

Multiple solenoid systems provide the ability to independently cycle the different banks of distribution pumps. This is most advantageous for transfer and long-feed progression applications when a certain number of pumps need to be cycled multiple times or at varying times throughout the stroke.

In cases where even greater control flexibility is required, Pax’s V-Series system should be considered.

Dual Lube Systems

These systems allow the user to select between two different lubricants, which are stored in separate reservoirs. The systems can utilize either a 6T, 10T, or 14T tankless system or a 6-6T, dual solenoid, tankless system in conjunction with any of Pax’s standard reservoirs. Lube selection, which reservoir the system will draw from, can be done via either manual or electronic valves.

Popular System Options

Advanced Control

Based upon the “dry contact” input described in the control description, the advanced control enables the user to cycle the distribution pumps, (regardless of their volume setting), in any of the following methods:

Simple Mode: 1 spray per cycle, (a cycle is when the dry contact closes and is then re-opened).
Counter Mode: 1 spray every pre-set number of dry contact closures.
Timer Mode: System will continuously cycle at a set rate or frequency, (frequency is the number of cycles per second), as long as the dry contact remains closed.
Multi-Spray Mode: The system provides a specific number of sprays at a set rate or frequency, (frequency is the number of cycles per second), every time the contract closes.

Note: Only one of the above modes can be used at a time and all of the distribution pumps on a standard, single solenoid system will cycle at the same time.

Power Cord and Plug

For the standard 110 V system, a nine-foot power cord with a three-prong plug can be provided.

Air Agitation since

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.

High Volume Distribution Pumps

The volume of lubricant sprayed by each Pax standard distribution pump can be adjusted to provide between 0.0023 and 0.0210 fluid ounces per spray (0.068 to 0.621 cc). This large range has proven to be sufficient for the vast majority of stamping applications. Applications requiring greater amounts of lubricant in a specific area can:

utilize multiple spray lines to apply lubrication to that area
utilize a digital timer to cycle the distribution pumps multiple times per stroke (up to a maximum of 300 cycles per minute)
utilize Pax’s high-volume distribution pumps

Pax’s high volume distribution pumps can be adjusted to provide between 0.0047 and 0.0420 fluid ounces (0.139 to 1.242 cc) of lubricant per spray. But, high-volume pumps have a lower output pressure than Pax’s standard pumps and are therefore not recommended for highly viscous lubricants.

Automatic Refill Valve Mounted on System Reservoir

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: The fluid that enters the system via the return line does not pass through this strainer.

Magnetic Base Limit Switch (P/N 00-1076-32)

This is an arm-type switch mounted on a magnet with a ten-foot cord connecting to a mating connector on a lube system. The arm can be actuated by the press ram or other device to provide the timing signal to the lube system.

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. Pax will supply a 5-meter long, M12, 4-pin connector cable with each sensor for the customer to utilize for this integration.

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.

Brass Ball Valves Connected to Distribution Pump Outlet

This arrangement replaces the quick connect fitting typically attached to each distribution pump, which eliminates the flow restriction created by the quick connect arrangement and enables the system to better spray high viscosity lubricant. An unrestricted flow ball valve will be connected to each distribution pump, a compression fitting (P/N 06-0910-20) will be connected to the outlet of the ball valve, and a nylon spray line will be directly connected to the valve via this fitting. The spray line will remain connected to the ball valve at all times and the valve will be utilized to shut off flow to this line when the line is not being utilized.
