Overview of BAW stainless steel sanitary centrifugal pump:
The
sanitary centrifugal pump is a single suction, single-stage, centrifugal
sanitary pump, which is suitable for conveying various liquids such as
milk, beverage, wine, etc. It is an indispensable conveying equipment in
food, chemical, pharmaceutical and other industries. The suction
temperature is about 80 º C. The high lift pump is especially suitable
for applications in systems with large resistance such as tubular
sterilization, yogurt temperature holding equipment, CIP cleaning, etc.

Structural features of BAW stainless steel sanitary centrifugal pump:
This series of sanitary centrifugal pump is mainly composed of pump body, pump seat and motor. Each part is connected by bolts.
The
support foot under the base plate can be adjusted freely for easy
installation without fixed installation foundation. During installation,
the outlet pipe can be installed in vertical or horizontal direction
according to different needs.
This series of pumps are designed with smooth transition, rigid structure and thick wall design.
In
the selection of materials, the pump body, pump cover, impeller and
other parts in contact with materials are all made of AISI316
Or AISI304 stainless steel.
The
mechanical shaft seal is made of high-quality stainless steel and
silicon carbide. It greatly improves the wear resistance and
moisturizing type, and prolongs the service life.
"ABB" motor with IP55. F insulation and wide voltage structure is selected.
During
fabrication, the pump body and impeller are precision cast integrally,
and all parts are surface treated. The dimension clearance shall be
ensured by special fixture during installation.
The shaft seal
adopts an open structure, so even if there is a small amount of leakage
at the shaft seal, it can be observed in time. The motor will not
overflow even if it is not detected for a short time. Thus, the service
life of the motor is guaranteed.
This series of pumps are fine and not easy to scale, especially suitable for CIP cleaning.
This
series of pumps has simple structure, convenient disassembly, low
noise, high efficiency, and gentle material handling, which meets the
requirements of food hygiene and ensures the original flavor of the
product.

Instructions for BAW stainless steel sanitary centrifugal pump:
During
centrifugal sanitary installation, the position of the pump is lower
than the suction liquid level (if the installation position of the pump
is higher than the suction liquid level, tank pump is required before
starting the pump). Before use, check whether the rotation direction of
the impeller is correct; Whether the nuts of the pump inlet and outlet
pipe joints are tightened; The sealing ring between the pump cover and
the pump body is well padded. The parts in contact with materials shall
be sterilized with steam before use to ensure food hygiene.
A
butterfly valve shall be installed at the pump outlet to control the
flow. Do not operate under overload for a long time to avoid damaging
the motor.
CIP cleaning shall be carried out immediately after the
pump is used to prevent material adhesion. If there is no CIP, manual
cleaning is required. During cleaning, hot water can be used first, and
then disassembled. Brush all parts of the pump in contact with materials
with a brush, and then rinse them with clean water. After cleaning,
install them in order.
If material drops on the ground behind the
pump casing during use, it indicates that the shaft seal is leaking. At
this time, the mechanical seal device on the shaft can be checked. If it
is severely worn or the seal is damaged, it should be replaced or
ground before use.
