Water Treatment Chemicals

Wax Emulsion
Lakeland have developed a range of polyethylene wax emulsions that are predominently nonionic in nature. We also have a montan wax emulsion available too. They are all completely aqueous emulsions. The emulsions are manufactured under pressure or by wax to water method. Some of the properties / advantages that wax emulsions can aid a formulator would be: ■ Ease of handling - Free flowing liquids with low viscosity that will blend with aqueous formulations. ■ Slip properties - Improved mechanical handling of packaged goods. ■ Lubricity -Increased stitching speed in fabrics. ■ Durability -Excellent ‘wearability’ in floor polishes. ■ Film forming - Added toughness in polymer coatings. ■ Aqueous based -No solvents contained, compatibility with aqueous systems. ■ Anti scuff - Surface coatings protected from abrasion. ■ Anti blocking -Coat to coat adhesion reduced.

Wernert NKPF Vertical Centirfugal Pumps
Seal-less side tank mounted vertical plastic lined pumps for aggressive and solid laden liquids. NKPF pumps offer the same stability as a metal pump due to the outer metallic construction. Having no bearing or shaft seal makes them suitable for liquids with a high suspended solids content.

Wetting & Dispersing Agents
Achieving premium high-gloss coatings and maximum hiding (coverage) power depends on two essentials: an optimized pigment particle size and the long-term stabilization of those particles within the overall formulation. Selecting the most effective dispersing agent depends closely on the pigment’s chemical nature—whether organic or inorganic—and on the resin system used in the formulation.

Wilden Bolted Plastic
A variety of elastomer options including Teflon® PTFE are available to meet abrasion, temperature, and chemical compatibility concerns. The Advanced™ Series plastic pumps are offered in polypropylene, PVDF and Teflon® PFA. A variety of options such as ANSI and DIN flanges and specialized air distribution systems are available to meet your specific application requirements.

Wilden Brahma
The Wilden Brahma Series pumps are specifically designed to transfer solid-laden slurries safely and effectively. With a unique top inlet and bottom discharge design, these pumps minimize the risk of damage caused by product entrapment or settling solids. Engineered with flap valves instead of traditional valve balls, the Brahma Series excels in handling large-size solids up to 76 mm. This design ensures seamless operation, even in challenging industrial and wastewater environments where reliability is paramount. Constructed from durable materials like cast iron and aluminum, these pumps are highly resistant to wear and tear. They support a broad range of operating conditions, including extreme temperatures and viscosities, making them an excellent choice for demanding applications.

Wilden Clamped Metal Pumps
Wilden’s Original Series AODD pumps are designed for utilitarian applications that require a robust construction. They utilise ProFlo which automatically optimizes air consumption and eliminates overcharging of the air chamber.

Wilden Stallion
The Wilden Stallion pump series excels in managing tough slurry applications due to its rugged construction and large internal clearances, preventing clogging from large particles. With a maximum flow rate of 764 l/min and a pressure capacity of 8.6 bar, it is ideal for handling abrasive and viscous materials. Constructed for portability, it features carry handles and a robust frame suitable for challenging environments. The pump's ability to operate under extreme conditions, including submersion, dry runs, and freezing temperatures, makes it versatile and reliable. This series also offers customizable elastomers, including EPDM, FKM, and Buna, ensuring compatibility with a wide variety of fluids and operational needs. Backed by ATEX certification, it is a trusted solution for safe use in hazardous areas.

Wilden Velocity
The Velocity Series pumps feature a groundbreaking design that allows the mounting position to be adjusted quickly and easily by loosening a single screw. This innovation ensures unparalleled flexibility for OEM systems and installations in tight spaces. Engineered for performance, these pumps provide enhanced suction capability compared to previous models. With an interchangeable mounting plate, they integrate seamlessly into setups with footprints matching select competitors and earlier Wilden models. Equipped with a smart air valve featuring just two moving parts, the Velocity Series reduces the risk of operational downtime. Its durable construction and versatile material options make it an ideal choice for a wide range of applications.
