Replacement of the mechanical seal of the pump Allweiler CTWH80-315/11 U3.3A-K1-W110

Replacement of the mechanical seal of the pump Allweiler CTWH80-315/11 U3.3A-K1-W110
Pumps of a well-known manufacturer Allweiler ALLHEAT are intended for the circulation of heat carriers such as grease or hot water at high temperatures (water up to 207°C or thermal oil up to 350°C). In particular, the NTWH/CTWH series pumps are single-stage horizontal centrifugal pumps with optimized bearing support, with spiral casing. Thanks to the long cooling section, no additional cooling is required. The massive slide bearing is pumped fluid lubricated, available in SSiC/SSiC or carbon/steel. The large area of the specially designed mechanical seal chamber prevents dry running. Before sealing the shaft, a safety gland and the following throttle section are installed. The following shaft seals are used in these pumps: Uncooled, balanced or unbalanced, according to DIN 24 960. Mechanical seal Product code U2.11A - balanced, Product code U3.3A - unbalanced (Burgmann 951534 037797000 AQ1VGG). Materials: moving ring - graphite A, counter ring - SiC, silicon carbide Q, spring - CrNiMo steel, sealing rings - fluorine rubber (FPM) V.

Purpose of submersible pumps

Purpose of submersible pumps
Borehole Pump is designed for regular water supply and is installed in various locations - on private plots, farms, and factories. There are many types of borehole pumps available on the market. To select the optimal model for specific purposes, it is necessary to study the principle of operation and construction of the borehole pump. Purpose of Submersible Borehole Pumps The borehole pump is considered a fairly versatile device. Its purpose is quite diverse: Complete provision of clean water for private houses; Ensuring the functioning of fire extinguishing systems; Irrigation of agricultural land; Raising the necessary pressure level in the water supply system; Filling aquariums and fountains with water; Filling large reservoirs - tanks, pools, wells. Using these devices allows lifting water from deep wells (up to 80 meters) to the surface. Industrial-purpose models can pump water from depths of up to 1000 meters. These pumps are characterized by impressive dimensions and high power. Compact pumps are used for private houses, but the operating principle of different types of borehole pumps is generally similar. You can buy a borehole pump in our online store.

Membrane pumps

Membrane pumps
Membrane pumps are used for pumping solvent in the production of plant protection products (SPP) and the suspensions and emulsions of SPP themselves. The flow part of the pump (collector, valves, seats) is made of chemically resistant plastic (polypropylene, PVDF). The pump is driven by compressed air, which guarantees safety during transportation of solvents. The equipment is made in explosion-proof design according to ATEX class 2G c IIC Tx, II2D c Tx, I M2 c T (150 C)
