|||||||||||||||||||||||||||||||||||||||||||||||||||||||
The RegSMART TM Cartridge regulator is a high pressure fluid regulator used for precisely controlling the fluid pressure (and flow) of viscous and semi-viscous materials. The unique modular “cartridge” design offers selection of three (3) different cartridge “ball and seat” sizes of 6 mm, 8 mm and 12 mm to achieve the desired fluid regulation. The modular cartridge concept results in a low pressure drop and easy to flush fluid passage design. The selection and interchangeability of cartridges gives the RegSMART TM regulator the flexibility for use in a wide range of materials and dispensing systems, not to mention the ease and quickness of repair. The RegSMART TM regulator is offered in two version of either an aluminum or stainless steel. This regulator is air operated with the adjustment of the fluid pressure requiring the use of a precision air regulator for constant control of material regulation. The pressure regulator is mounted in the fluid circuit between the pump fluid outlet and the gun or dispensing valve fluid inlet, enabling you to accurately control the material pressure/flow to the gun or dispense valve. Extrusion and Spraying applications often require a uniform fluid pressure with minimal fluctuations. The RegSMART™ regulator produces a consistent and regular bead size in an extrusion process or a constant pressure to give an even material thickness in a spray application. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

Features & Benefits of THOR Air Motor: The Power House | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
KREMLIN REXSON manufactures a full range of motors to ensure optimized air fluid ratios. It is important to be sure you always have sufficient material pressure to move the material being processed to the dispensing valve. The restriction to your flow is called “Back Pressure” and is due to material viscosity and hose diameter and length. The power of the motor/pump combination is key to your success. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

MAIN ADVANTAGES OF A THOR AIR MOTOR DESIGN | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
• Quiet operation • Thru-shaft air motor provides support to the piston shaft • Balanced volumes on the top and bottom of the air cylinder provides equal force • Large diameter exhaust port minimizes icing risks • Existing pneumatic connections making remote stop/start easy to configure • Air supply to reversing valves either regulated or full air pressure • Externally fitted air reversing valves |

Features & Benefits of Chop Check Pump: The Heart of the System | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
KREMLIN REXSON manufactures a full range of extrusion pumps to handle most high-viscosity materials. These pumps are double-acting reciprocating pumps and are recommended for use on materials over 5,000 cps or for use on products that do not self level. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
KEY FEATURES | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
• Large internal fluid passages optimize material flow-resulting in low shear and minimal material degradation. • Pumps are designed with as few parts as possible to simplify maintenance. • Pumps are designed and manufactured for severe-duty applications - "EVER TOUGH" parts. • Pump fitted with PTFE + PE seals as standard with PTFE - Graphite and PU seal kits available as an option. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||
EFFICIENCY | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
All KREMLIN REXSON pneumatic pumps are able to stop when the dispensing valve is closed. This is called “stalling.” As soon as the dispensing valve is reopened, the pump will automatically restart. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
DOUBLE-ACTING RECIPROCATING PUMP | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
PISTON DOWNSTROKE…Check valve (green) closed against the seat and the material in chamber V2 is displaced out of the pump by the pump displacement rod. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
PISTON UPSTROKE… Check valve (green) opens and material is forced into chamber V2 by the priming piston (From V3). The top check (red) closes: pushing material from chamber V1 to exit pump outlet. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||
• Modular pump design using the minimum number of components • Hard chrome finish to pump shaft and cylinder • New type guard (with integrated large diameter wet cup) compliant to EU norms • Simple design using external reversing valves • Very fast changeover • Large diameter exhaust making for quiet running and minimum icing risk |

Selecting a Ram & Follower Plate | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
An elevator is a device that lifts up and lowers equipment but it does not force the pump into the material, the only force you will get from an elevator is gravity assistance from the weight of the pump. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||
You can use both single seal or double O-ring seal follower plates: • Single Seal follower plate will allow you to process materials with a viscosity ranging from 3,000 and 300,000 cps. • Double seal follower plate will allow you to go up to 1 million cps depending on material output. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||
The follower plate has three functions: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
1. To provide positive priming to the pump, by helping the material flow towards the pump inlet. 2. To seal the material in the drum. This is critical using moisture sensitive or to simply to protect the material from outside contaminants. 3. To provide a clean wipe to the drum. This ensures that the material is "wiped clean" from the drum sides to reduce material waste. |

Practical Information: Viscosities | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
Usually expressed in Centipoise (cps) or Poise (ps). The current units are in the "milliPascal/second.” Other units used: Centistoke, Engler, Saybolt, Gardner... We have included some measures of viscosities as examples. A Brookfield Cone viscosity meter was used to measure the viscosity. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

Material viscosity can vary significantly with temperature, often the colder a material gets the higher the viscosity. That means the more power you may need from your air motor to pump the material. This may also have a bearing on the type of ram, follower plate and hose that you select. It is for this reason material manufactures always provide data on the correct use and storage of their products, including an ambient temperature range for correct material processing.It is important for you to be aware of these facts and operate within the parameters. You will also find that there is often a difference between starting to pump a material and when the material is actually flowing. This is called static flow or dynamic flow. When you start, the pump has to have sufficient power to overcome the material surface tension inside the system (the internal friction to flow due to back pressure). Once the material is flowing, the drive pressure can some times be reduced. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
|

Practical Information: Pressure Drop | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||
Pressure drop is the resistance that prevents material from moving forward in the pipe. Two pipe variables influence this resistance: the (inside/internal) diameter and the pipe length. The pump will generate a pressure, strong enough to move the fluid material through the pipe (or hose) to the material pipe outlet. This pressure must be enough to overcome the original pressure drop. While it is hard to reduce the pipe length, it is relatively easy to select an appropriate internal pipe diameter. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
