How It Works

In its basic form, PerfectFlow is functionally both a fluid containment device as well as a fluid transfer device. PerfectFlow is fully scalable from less than a milliliter in capacity to over 12,000 gallons. PerfectFlow's materials of construction range from mild steel to stainless steel to composites. The PerfectFlow system has a sealed fluid containment and dispenser suitable for fluids ranging from liquids to highly viscous semi-solids. It includes an internal piston within the fluid containment. Pressure applied to the piston is pneumatic, hydraulic, mechanical, electronic, or electro-mechanical and is the motive force to dispense a fluid. The PerfectFlow system's key benefits include the ability to be self-powered, high speed, and contamination free.

Details

While this diagram depicts a bottom fill/bottom discharge configuration, there is also a top fill/top discharge configuration. In the top fill/top discharge configuration, (piston) includes a central hole and an internal fill/discharge tube runs from the top to the bottom of the container through the piston.

Collar

The collar protects the service valve, and has holes in its side to allow visual access to a pressure gauge that can be installed in the service valve’s 10% port. The collar is robust enough to permit mechanical lifting.

Sight Glass

Designed for use with a laser measurement inventory system.

Product Marking

PerfectFlow containers are marked with colored tape to designate the product inside. The PerfectFlow color for grease is black.

Footring

There are holes in the footring that allow easy access to the ¾” ball valve from the front.

Service Valve

This valve has three ports: POL port, 10% port, and safety valve. Nitrogen is introduced into the container through the POL port. A pressure gauge can be attached to the 10% port. The third port is a safety valve that vents excess pressure.

Nitrogen Pressure

Maximum nitrogen pressure of 120 psig is introduced into the container through the service valve and pushes the grease from the container.

Container

DOT 4BW-225 manufacturing specification. The container can be used to haul grease under pressure on public roads. It has a capacity of 165 pounds of grease. Its empty weight is approximately 88 pounds.

PerfectFlow Grease Piston

The PerfectFlow grease piston ensures that the grease is uniformly pushed out
of the system.

Grease

The PerfectFlow grease systems will handle any grade of grease.

Valve Assembly

The valve assembly terminates with a ¾” ball valve.

Some of the problems that PerfectFlow addresses are as follows:

Handling Messy Pumps

Users never handle a thick-fluid pump because the system either replaces the thick-fluid pump altogether or, if an auxiliary pump is required, it is permanently located and connected to the system with a quick-connect fitting

Uncontrolled Product Discharge

Eliminates the hose-reel problem of uncontrolled retraction in combination with an open preset meter by eliminating hose-reels and providing increased functionality

Punctured or Crushed Containers

Eliminates the costs and problems from fluid containers being either pierced by forklifts or crushed by heavier equipment

Messy Filling of Dispensing Guns

Users will more quickly, more easily, and much more cleanly refill thick-fluid dispensing guns

Messy Disposition of Disposable Containers

Eliminates the mess attendant to proper disposition of disposable fluid containers because the system eliminates disposable fluid containers

45-Minute Container Change-out Time

Reducing container change-out time by 95% by eliminating inserting and removing fluid pumps from the fluid container and the system's quick-connect fittings

Dispensing Rate Too Slow

Dispensing rates can be extremely fast or extremely low, varying from 870 liters per minute or more to less than 0.01 liter per minute as required by the application as a result of the system's energy, which can pneumatic, hydraulic, mechanical, electronic, or electro-mechanical

Product Spills

Reduces slipping accidents by preventing product spills due to the system's clean operation

Remote Location with No Power

The system operates independently dispensing fluids with no external power source using instead the system's internal energy as a motive force

High Container Residual

Product residual is minimal because the invention's internal force element dispenses nearly all the product in the fluid containment

Workers' Compensation Claims

Lowers user worker's compensation claims by providing a cleaner, safer work environment

"Kitty Litter" Product Contamination

Product is not contaminated by the "kitty litter" acquired when pumps are changed from empty containers to full containers because the invention eliminates removing and inserting of fluid pumps

Product Waste

Unit volume purchases are reduced by up to 30% through waste minimization

Paying for Product Left in the Container

End users pay only for the product they use because suppliers' weigh systems in and out

Follower-Plate Hang-up

The system eliminates follower-plate hang-up costs through its unique internal design where the system's force element does not touch the container sidewalls

Necessity to Bleed Lines

Product lines do not need to be "bled" before resuming production because the system eliminates air pocket contamination

Hose Reel Installation and Maintenance Costs

The system eliminates hose-reel installation and maintenance costs because the system eliminates the need for hose-reels with equal or better functionality

Dented Drums, Kegs, and Pails

The system's more robust containers eliminate dented drums, kegs, and pails

Air-Pocket Contamination

The system eliminates air-pocket contamination which is deleterious to pump operation

Pulse Dampners

Production line pulse dampeners are not required because the system provides non-mechanical (no moving parts), non-pulsating product dispensing and transferring

Too Costly to Modify Fluid System

 Users can more easily and more quickly modify, reduce or expand their operational fluid transfer capability without installing or removing piping because the system is self-contained and is available in a flexible configuration and sizes - fully scalable in portable, bulk, and portable/bulk containers

Limited Asset Utilization

Enables industrial users to generate more revenue from their physical space because of the system's portability

Environmental and product contamination costs and worker compensation claims

The system eliminates the need to insert and remove pumps from thick fluids

Environmental and product contamination costs and worker compensation claims

The system eliminates the need to insert and remove pumps from thick fluids

Hard to Move Containers

Portable because its portable segment is easily moved by way of its hand cart for industrial applications

Pump Failures Too High

Increases fluid system reliability because the invention eliminates fluid pumps

Pump Priming

The system does not require priming and uses no internal pumps

Short-lived product quality

Product quality is maintained longer because the system is sealed and an inert gas protects the product from oxygen and other contaminants

Messy Disposable Fluid Containers

Enhances waste minimization because the system eliminates disposable fluid containers

Lack of Operational Information

Smart Systems enable users to remotely assess their operational effectiveness by receiving and processing information from the technology's in-field fluid systems equipped with sensors and communication capability

Can't Get Prospective Customer's Attention

The system is a superior marketing tool because prospective users easily identify with the invention's benefits and readily pay a product premium to have such benefits

Poor Dispensing Rate Control

The invention can dispense thick fluids at a constant, ratable rate because the system is non-pulsating

Too Difficult to Use System

The system is very user friendly and compatible with union shops

Messy Work Environment

Containers are 100% recyclable, and the work environment is kept clean with the sealed dispensing system and elimination of internal pumps

Noise Pollution

The system is extremely quiet - makes no noise while dispensing a thick fluid or paste - because the invention has no moving parts

Portable

This is an example of the portable segment of the system applied to fluid distribution. This is a portable PerfectFlow container for 165 lbs of grease using a 15:1 grease pump for use with various types of grease fittings. For applications that do not use grease fittings, no pump is required. 

Bulk

This is an example of the portable-bulk segment of the system applied to fluid distribution. In this picture, the smaller container is on a scale being refilled from a larger container. On the left is a PerfectFlow 300-gallon bulk container. The largest PerfectFlow bulk containers currently in the field are 12,000 gallons. The smaller PerfectFlow container on the right with a capacity of 55 gallons is sitting on a trolley and both are sitting on scale.

Portable / Bulk System

Current PerfectFlow bulk containers range in size from 7 gallons to 12,000 gallons. All PerfectFlow containers are sealed, refillable, and reusable. All PerfectFlow containers are DOT or ASME approved.

PerfectFlow containers can be used separately or connected together in a refilling system. Containers can be refilled on site or returned to the fluid supplier for refilling. 

Dispensing Gun

This is an example of the filling apparatus for a PerfectFlow thick fluid dispensing gun as attached to the portable segment of the system.

For several decades, CHI TECH's technology has been applied to the Oil Bank® and Grease Bank® products. These products are used to transfer lubricants, specifically lubricating oil and grease. 

Today, these systems are simply called PerfectFlow.
