The soaking-up pressure head sleeves (them also call the reinforced hoses) use for filling or pumping out of water from pools and tanks, and also at elimination of consequences of various floodings.
Are applied to absorption and forcing of various liquids.
Are efficient at t°ot-35 to +90 °C.
Class "B" - for gasoline, kerosene, fuels, oils on an oil basis;
Class "B" - for technical water;
The class "KShch" - for weak solutions of inorganic acids and alkalis of concentration to 20%;
Class "P" - for feedstuffs (milk, beer, alcohol, wine, subacidic solutions of organic and other substances, drinking water).
Sleeves pressure head soaking up
Sleeves the rubber pressure head nearmirovany GOST 5398-76 which are soaking up with a textile framework are applied to absorption and forcing of various liquids,
Sleeves with a textile framework, with a metal spiral have on the ends soft cuffs for accession to fittings. Are made smooth and corrugated. There are two groups:
1 group - the sleeves which are soaking up working vacuum of 0,08 MPas.
2 group - sleeves pressure head soaking up with working pressure of 3; 5; 10 kg/cm2.
Sleeves are made the following classes:
