The REXSON pumps of the high viscosity range have been designed with robustness in mind, and the aim of offering a high degree of modularity to follow your application. Unlike liquid fluid pumping, the high viscosity range imposes highly variable mechanical stresses from one product to another.

Double-acting ball pumps are similar in construction to pumps for liquid products and are capable of transferring fluid up to 50,000 Cps. These pumps have been adapted for high viscosity products by optimizing the passage diameters, the nature of the seals, and the hardness of the materials.

To create your own pump that will meet your application specifications, you will have to select:

The correct air motor according to the maximum pressure,
The construction materials according to the nature of the product,
The foot and mounting style according to the product packaging, and your installation
The Seal pack (see the Documents tab to get all necessary information on our website).

Our air motors are designed for maximum airflow with a pilot distributor to allow fast inversion. They are equipped with a broad silencer to avoid water freezing at the motor outlet and can be controlled (start / stop) from a remote air control.

These pumps are used as feeding equipment directly from the product packaging in-wall mounting or installed on an elevator with a follower plate for open drums.

High Viscosity 2 Ball Pump used for Airless® and extrusion applications. The pumping solution offers a small to mid-size footprint and its stainless-steel construction with optional carbide seat and different seal pack options work for all materials, including abrasive.

You can customize your pump with the right air motor size and create your own part number. We suggest you contact our experts to help you select the right configuration to fit your needs. You can also consult our Documents tab, our Configurator, and the complete catalog.

Materials

Grease Graphite

Solid lubricating additives, including graphite, are added to some grease to improve its lubricating properties.

Grease Silicone

Silicone grease is commonly used for lubricating & preserving rubber parts, such as O-rings. Additionally silicone grease does not swell or soften the rubber, which can be a problem with hydrocarbon-based grease. It functions well as a corrosion-inhibitor & lubricant for purposes that require a thicker lubricant. Thermal grease often consists of a silicone grease base along with added thermally conductive fillers. It is used for heat transfer abilities rather than friction reduction.

Silicone Two-Component Sealant

Silicone sealants can be used in two or three components for increasing mechanical capabilities.

Silicone Sealant

Silicone sealants are used to protect & seal anything from the smallest silicon chip to the world's tallest skyscrapers.

Polyurethane Sealant

Polyurethane Sealant is abrasion resistant, odorless, remains flexible at low temperatures & is 100% urethane. It's quick & simple to use with its fast-setting capabilities that help to reduce downtime. The balanced, low-viscosity liquid components form an easy-to-use paste.

Polyurethane Sealant with Accelerator

Accelerator speeds up the setting process for 1K sealant to achieve rapid rain resistance & thorough setting of the accelerated foundation sealant.

Polyurethane Two-Component Sealant

Polyurethane Two-Component Sealant can be used in two or three components for increasing mechanical & chemical capabilities.

MS Polymer Sealant

Silyl modified polymers (SMP, also silane-modified polymers, silane-terminated polymers) are polymers (large, chained molecules) terminating with a silyl (SiH3) group. SMPs are the main components in solvent-free & isocyanate-free sealant and adhesive products. Typically the sealant products manufactured with silyl modified polymers have good adhesion on a wide range of substrate materials, and have good temperature & UV resistance.

Hybrid Sealant with Accelerator

Polyvinyl Chloride (PVC)

Used for waterproofing, anti-ship for Under Body Coating (UBC),under body sealing (UBS) or Interior sealing.

Hybrid Sealant

Today polyurethane & silicone sealants are considered "high performance products." They deliver a significant adhesion, a good movement capability & are durable. However, these high performance products do have their limitations & disadvantages.

Adhesive STP

STP Polymers are the new generation environmentally friendly polymers that are replacing the isocyanate & solvent containing polyurethane resins to produce sealant & adhesive products that are safer & greener for the consumer & tradesman.

Adhesive Polyurethane

Polyurethane (PU or PUR for short) is not a single material with a fixed composition, but instead a range of chemicals sharing similar chemistry. It is a polymer composed of organic chain units joined by urethane or carbamate links. Most polyurethanes are thermosetting polymers & do not melt when heated unlike thermoplastic polyurethanes which do.

Adhesive Hybrid

Hybrid Adhesive Sealants are one component formulations that form robust, permanent & flexible bonds offering great adhesion to many materials for reliable performance, are paintable when wet for fast process time, have a fast skin time for a tack-free surface, are isocyanate-free for reduced health & safety concerns & resist degradation from sunlight for excellent aesthetics.

Adhesive 1K Accelerator

Additional accelerator used for polyurethane or silicone adhesives speed up the chemical reaction between the adhesive & the material they are bonding. Used often in the field where temperatures are lower to accelerate the bonding times.

Adhesive Polyurethane Multi-Component

Two-component polyurethanes (also called 2C PUR) have the advantages of single component polyurethane adhesives, but cure more quickly through larger gaps & are not dependent on moisture/heat for curing.

Adhesive Acrylic

Adhesive acrylics were developed for structural bonding applications that require tensile, shear & peel strength combined with maximum impacts, stress & shock resistance.

Adhesive Silicone

In general, users can count on silicone adhesives to produce bonds that can withstand high temperatures (in some cases up to 600°F), remain flexible even after curing & resist chemicals including water.

Adhesive Butyl

This adhesive is highly resistant & aggressive sticking to almost any substrate despite its easy fit application properties.

Adhesive Silicone Multi-Component

Two-component silicone has the advantages of single component silicone adhesives, but cure more quickly through larger gaps & are not dependent on heat for curing.

Adhesive Epoxy

Epoxy adhesives, dependent upon the specific chemistry of the system & nature of the cross-linking available, adhere to a wide variety of materials. Some of the most important performance requirements include exceptional chemical & heat resistance, excellent adhesion & water resistance, as well as satisfactory mechanical & electrical insulating properties.

Adhesive MS Polymer

MS Polymers are the next generation of silicones & mastics. Unlike their counterparts these products adhere well to most substrates without the use for specific primers. By using these products you can reduce the risk of application mistakes.

Adhesive Epoxy Multi-Component

Two-component epoxies feature unique versatility in application & performance. These systems consist of a resin & a hardener that can be formulated to offer a wide range of mechanical, thermal, optical & electrical properties.
