Today, many demanding industrial sectors need sealing systems that guarantee safety for both people and facilities. It is very important to offer quality products that are resistant to extreme conditions such as high pressures and temperatures and that also guarantee impeccable sealing. This safety is ensured by using single and double cartridge seals for sealing corrosive and/or abrasive fluids containing heavy solids or sticky fluids with scant lubrication. The correct selection of the cartridge seal design and its materials, the use of flush, quench, ring and pumping connections, among...

It is just as important to use a product that is technically suitable for the application as it is to be able to install it easily and safely. With this objective in mind, the cartridge seals shown in this catalogue have been designed to reduce all possibilities of error to a minimum during the installation process and also prevent damage to other pump components.

Relevant Characteristics Some of their most important features are: •The use of solid contact surfaces to prevent possible deformations, with the ensuing loss of flatness. •The O-ring that seals the shaft is static. It avoids the fretting effect on the shaft and its subsequent repair. • Contact surfaces with an anti-rotation pin to prevent them from sticking together (sticky fluids, dry startups) and turning in their housings.

•The springs for compressing the conThe tact surfaces are isolated from the product, which prevents them from becoming blocked by products containing particles, pastes, etc. They are made of Hastelloy material and have great chemical resistance and mechanical properties superior to those of stainless steel. • A flat self-adhesive seal that facilitates the positioning and prevents failures during the installation process. •Contact surfaces made of sintered silicon carbide (Q1), suitable for working with the most aggressive products in the chemical industry. • Self-centering clips that assure...

Instalation costs: Operating costs: Hiderinq SAFE INDUSTRY — They require no maintenance; unlike braided packing, the cartridge requires no re-tigh tening.

• They reduce the pump power consumption. • There are no product leaks.

CHARACTERISTICS: • Unbalanced • Not dependent on the rotation direction. • Wave spring OPERATING LIMITS: d1 = 24 - 95 mm p= 10 kg/cm! v= 20 m/s t= -15- +2000C (*) (*) The temperature resistance depends on the material of the secondary seals used. The operating limits are defined by the PV factor which is determined for the sealing system characteristics and those of the application. DESCRIPTION: Single cartridge in which due to its geometry, the rotating part has a wave spring to prevent it from blocking when in contact with viscous fluids or fibres. Hiderinq SAFE INDUSTRY —

(*) The temperature resistance depends on the material of the secondary seals used. The operating limits are defined by the PV factor which is determined for the sealing system characteristics and those of the application. DESCRIPTION: A single cartridge seal that permits the injection of external fluids (quenching and flushing) and the recirculation of internal fluids (flushing). The rotating part of the seal has a self-cleaning metal bellows structure....
