The Fristam water pump mechanical seal offered by Shaanxi Daolin Mechanical & Electrical Co., Ltd. is a replacement seal designed for shafts of 20 mm, 30 mm or 35 mm diameter. It operates between - 20 °C and +180 °C, tolerates a maximum pressure of 1.0 MPa and a shaft speed of up to 15 m/s. The stationary and rotary rings are available in carbon, silicon‑carbide or tungsten‑carbide, while the secondary seal can be NBR, EPDM or Viton. Springs and metal components are supplied in stainless‑steel grades SS304 or SS316, and the seal is suitable for water, oil and other moderately corrosive fluids.
In the pump‑seal market, carbon and silicon‑carbide rings are the most common choices because they balance wear resistance with cost. Typical mechanical‑seal designs also specify a secondary sealing lip of Viton for oil‑based applications and NBR for water‑based service, matching the material selection listed by Daolin. Standard operating temperature limits for such seals are - 20 °C to +180 °C, and a pressure rating of 1.0 MPa aligns with the usual specifications for medium‑pressure centrifugal pumps. Conventional packaging consists of a tissue‑paper wrap inside a cardboard box, which Daolin also offers per customer’s requirement.
End users include pump manufacturers, plant maintenance teams and industrial fluid‑handling facilities that need reliable seal replacement. The supplier ships the seals by express couriers such as DHL, UPS or FedEx, and also accommodates air or sea freight when bulk quantities are ordered. Buyers should confirm the exact shaft size, material preference and required secondary seal type before placing an order to ensure compatibility with existing equipment.

Before confirming a purchase, the buyer should verify the exact shaft diameter required for the pump and match it with the 20 mm, 30 mm or 35 mm options offered by Shaanxi Daolin. It is also important to confirm the fluid type, ensuring that water, oil or other moderately corrosive liquids fall within the seal’s material compatibility. Request a material data sheet that lists the carbon, SiC or TiC composition of the rings and the secondary‑seal material chosen.
Daolin states that shipments can be arranged by express carriers such as DHL, UPS or FedEx, and that air or sea freight is also available for larger volumes. The buyer should ask for the Incoterms that will apply - for example FOB Xian port or CIF Shanghai - and confirm the expected lead time, which typically depends on the chosen shipping mode. Payment terms are not published, so request the supplier’s standard conditions, often a 30 % advance with the balance payable against documents.
Because the seal is supplied without a pre‑tested certificate, the importer should arrange a third‑party inspection to verify the ring hardness and dimensional tolerance before shipment. Request a mill test report that confirms the carbon, SiC or TiC composition and the hardness values typical for mechanical seals. Upon arrival, compare the received dimensions with the specified shaft‑diameter range and inspect the secondary‑seal material for any signs of damage or ageing.
