Water blasting is the use of water with high pressure and high speed to clean and treat various surfaces. It can also be used to cut through many different solid materials like steel and concrete. The advantage with water cutting compared to laser cutting is that generated heat is transported away by the water, hence it works for some sensitive materials where laser cannot be used. The high pressure is achieved by an engine and a pump, and when the water passes through a small nozzle/orifice it gets the speed that does the work. The water used can have different additives like detergent chemicals or abrasives, where it is needed. In many applications plain clean water can be used, which makes it an environmentally friendly method. The equipment for water blasting consists of a motor, a pump, water tank, valves, hoses and nozzles. Since the pressure rating is up to 6 000 bar the requirements for the included components are high. Not only the pressure, it should in some applications also withstand extreme temperatures, abrasives and also work in harsh environments with abrasion, seawater, ozone, chemicals and high/low temperatures. WOMA has been producing water jetting equipment for more than 50 years which are made for removal, cleaning and cutting, and are able to supply stationary as well as mobile units. They are delivered all over the World.
WOMA relies on Parker hoses WOMA rely on Parker hoses and fittings when building the equipment. The choice of Parker components is based on Parkers high quality and the fact that WOMA deliver products worldwide it is an essential requirement that the hoses and fittings are globally available. The hoses that WOMA uses are Blastopac ½” rubber hoses and Blueline ½” thermoplastic hoses with pressure ratings up to 6 000 bar which also meets the requirements of the global specification DIN EN 1829/2.
Parker Blueline hose range Blueline is the series of thermoplastic ultra-high pressure hoses with the following characteristics: It has up to 35 % less weight compared to rubber hoses which makes the daily work greatly facilitated. It is resistant to many chemicals and abrasion in tough environments, which guarantees a long service life. The Blueline series with the hose types 2388N and 2580N provides a coherent series together with the matching fittings from Parker Polyflex. Another advantage of Parker hoses is their worldwide availability.
Parker Blastopak Parker Blastopak Hose is a completely new hose range with improved performance for water-blasting applications. The high performance is a result of the design with four or six spirals that better meets the requirements of water-jetting and blasting applications and also conforms to safety. With its high working pressure from 800 bar in size -16 up to 1 100 bar in size -4 to -12, good flexibility combined with dedicated interlock fittings is the right choice to ensure better performance and safety at the same time. The safety factor burst/working pressure of 2.5:1 makes the hose meet the requirements of global specification DIN EN 1829/2 (impulse) in all common hydraulic applications.
WOMA – Certified Distributor of Parker’s Ultra-High Pressure hoses WOMA is a Certified Distributor of Parkers’ ultra-high pressure hoses and fittings with a facility in Durban. In this facility hoses and fittings are assembled in order to serve the South African market. The presence in South Africa gives WOMA an advantage over competitors since the local experience makes WOMA know their customers and their requirements better. WOMA will supply the right hose, at the right time.
"We have supplied Parker's Thermoplastic and Blastopak products with our unit builds for over 25 years. It gives us a sense of security that enables us to guarantee the quality of our products to our customers, with after sales service beyond the norm. Without long standing service to the industry, coupled with a vast knowledge and experience gained over this long period, Woma is rightly perceived as a reliable partner. Together with our experience, knowledge, and proximity to our customers, Woma is a reliable partner. We are also quick to respond to customer requests and we can deliver both components and spare parts in a short time period.” Andrew Stocks from WOMA SA.
