The MX series is used in many sectors in the transfer of liquids with viscosities from 1 to 100,000 cPs.
In the case of medium/high viscosity products, it can be used for metering services with the aid of frequency variators or motor variators, also electrically servo-controlled with a 4 ÷ 20 mA signal or pneumatically with a 3 ÷ 15 psi signal.
The construction of this series of gear pumps complies with the the 2006/42/CE, 2014/30/UE, 2014/35/UE directives and the UNI EN ISO 12100, UNI EN ISO 13732-1, UNI EN 809, UNI EN ISO 14847 standards. On request versions compliant with the 2014/34/EU (ATEX) directive and with the API 676 – NACE MR0175 standards; it is also available with EAC (CU TR 010) – CU TR 012 certification.
The management of the quality system of Pompe Cucchi Srl operates in accordance with the UNI EN ISO 9001: 2015 standard.
APPLICATIONS
The main applications of the MX series transfer pumps are:
CHEMICAL SECTOR
The transfer and metering of any type of liquid with the absence of solid suspensions.
AGRICULTURAL SECTOR
The pumping of molasses and other liquid products for animal feeding.
FOOD INDUSTRY
Transfer of liquids in the primary transformation processes – the pumping of chocolate (for this use a series has been specially created with a preheating chamber with a very large surface to favor the heat exchange between water at 55°C and the hydraulic chamber) - fats - jams etc.
INDUSTRIAL SECTOR
The pumping of glues, resins, bases, acids, isocyanates, polyiols etc.
CONSTRUCTION FEATURES
The standard version is in AISI316L stainless steel with an anti-wear – anti-seize-up heat treatment that makes the component parts of the pump black (“black” treatment).
MATERIAL
The MX series pumps are made of AISI316L stainless steel.
Shafts and gears are subjected to a particular anti-wear and anti-seize-up heat treatment.
SHAFTS AND GEARS
The construction standard foresees gears and shafts in AISI316L.
For particularly onerous applications it is possible to supply the pump with “HH” (High Hardness) treated gears and shafts.
SPECIAL TREATMENT
With this special treatment it is possible to give the treated parts greater resistance to chemical corrosion, a very low coefficient of friction and very high resistance to wear.
The supporting takes place using filled PTFE bushings or self-lubricating sintered material depending on the type of application. The seal can be made with packings (design temperature 300°C) or with simple or double mechanical sealing (design temperature 200°C) in various materials selected based on the chemical and physical characteristics of the pumped product. The standard connections are provided with BSP thread for sizes between MX5 and MX40 and with oval threaded BSP or weld-in counterflanges for sizes between MX50 and MX150.
INTEGRATIONS
All models can be integrated with ANSI or DIN flanges.
Unless otherwise specified, the direction of rotation of the pump is clockwise (pump seen from the shaft output side); upon request, mechanical seals suitable for anticlockwise or reversible rotation can be assembled. The MX type models in the standard version are built in AISI316L with an anti-wear – anti-seize-up heat treatment that makes the component parts of the pump black (“Black treatment”).
For the food sector, on request it is possible to assemble gears in plastic material approved by the FDA and to avoid this treatment (“Black treatment”). On request it is possible to equip the pump with a preheating chamber and/or a built-in safety valve. The pumps of this series can be supplied with a bare shaft or with a base and alignment to motors, gearboxes or variators with construction in accordance with CE regulations.
