Mexico Q-PUMPS centrifugal pump QIS internal balance mechanical seal
The QIS series is a new generation of sanitary grade direct coupled centrifugal pumps launched by Q-Pumps (Queretaro, Mexico), designed specifically for hygiene conditions such as food, beverages, and pharmaceuticals, while also compatible with non sanitary industrial scenarios17Core certification includes3A 1004/02-10、 FDA、EHEDG， Fluid contact surface standard Ra ≤ 0.8 μ m (32 μ in), standard 100% electric polishing, meets strict hygiene requirements15Compatible with NEMA/IEC motors, 50/60Hz universal, with the same size mounting base as QC+series, can be directly replaced and upgraded17.
overcurrent component: All316L stainless steelSemi open impeller, with suction in the middle of the volute and a 360 ° rotation at the discharge outlet; Standard sanitary clamp interface, optional inclined seat NPT、 Flanges, SMS, DIN, etc; The support base and feet are made of 304 stainless steel, and the adjustable height feet are easy to level15.
sealed system: Full range configurationInternal balance mechanical seal(Single/double seal optional), including QIS+upgraded built-in balanced seal, no need for external flushing, more suitable for sterile environment; Newly designed back cover improves drainage and reduces hygiene blind spots12.
connection methodDirect connection design, stainless steel adapter directly connected to motor flange, no need for coupling alignment, quick disassembly and assembly, compatible with CIP/SIP cleaning process2.
Food and beverage: dairy products, fruit juice, beer, wine, edible oil, sauces;
Pharmaceuticals and cosmetics: purified water, pharmaceuticals, alcohol, injections, ointments;
Other: CIP/SIP cleaning cycle, sterile water transportation, fine chemical intermediates (non sanitary conditions).
advantageElectropolished surface is corrosion-resistant, easy to clean, and reduces bacterial residue; Internal sealing design reduces maintenance costs; Semi open impellers are not easily clogged and are suitable for fluids containing small amounts of soft particles; Complete drainage without any hygiene blind spots; Direct connection structure is efficient and energy-saving, with small installation space17.
maintainTo avoid damage to the seal caused by idling; Regularly inspect the sealing surface and O-ring; Spare parts have strong universality, and vulnerable parts such as seals and impellers can be quickly replaced; Select single/double seals based on medium temperature, viscosity, and pressure to extend service life.
