Bellin produces products and solutions for the industrial sector in the field of water treatment, winemaking and agro-food. In particular, it specializes in the design and development of progressive cavity pumps, lobe pumps and macerators for a wide range of applications.
Bellin progressive cavity pumps have been designed for easy, low maintenance: wear parts can easily be replaced on the site. Eccentric screw pumps are heavy duty pumps and they can be used to pump abrasives sludges, viscous products, oils, emulsions etc. Due to the steady non turbulent flow they can also handle shear sensitive products and medium with solids content without breaking up the solids.
ADVANTAGES
Bellin progressive cavity pumps have many advantages over other types of pumps which allow use extremely diverse:
self priming up to 7-8 mt
low speed and so longer pump life (200-500 r.p.m. in comparison to 1400-2800 r.p.m of the centrifugal pumps)
suitable to transfer abrasive and higly viscous products
steady flow with minimum pulsation and low shear effects
high abrasion resistance
minimum maintenance
low noisy
capacity up to 260 mc/h
pressure up to 30 bar
direct relation between conveying capacity and speed makes the Bellin pumps suitable also for dosing purposes.
Bellin Rotary Lobe Pumps type “PL” have following features:
– Compact construction: space saving;
– Self-priming up to 7-8 mt.;
– Dry running for short periods;
– Reversible operation;
– Easy maintenance – maintenance and cleaning on site: fast opening of the pump because of the possibility of removal of the front inspection cover without disturbing the pump housing or pipe work;
– Pump housing can be supplied with hard metal replaceable wearing plates at front and rear; they can be replaced easily on site;
– Possibility to handle large solids particle up to 25 – 30 mm.
PUMP HOUSING: in grey cast iron (type PLG)
with replaceable hard metal wearing front plates (PLGP);
with replaceable hard metal wearing front-radial plates (PLGR);
oenologic execution (PLWXF) food-grade alloy pump housing with stainless steel plates.
LOBES: covered with NBR rubber, EPDM rubber, FPM rubber, Other on request;
MECHANICAL SEAL: ceramic or tungsten carbide self-lubrificated (PLG, PLGP) – replaced on-site without disassembly of the pump housing and piping (Easy Maintenance) for execution PLGRH;
CONNECTIONS: flange according to UNI/DIN – ANSI, oenological type “garolla” – DIN – SMS – ball joints, other on request.
Bellin BMG Pipeline Macerators are designed to fit into the suction line of raw sewage or sludge pump, homogenizing the medium to improve downstream process, whilst protecting high performance pumps from tramp and rag debris in the medium. It is a disintegrating device for raw sewage and sludges up to 6% solid matter in a pipeline under operating conditions ranging from – 1 bar to + 4 bar. The range consists of a conditioning cutterhead co-axially mounted specifically designed to handle raw sewage and sludge. The cutters consist of a steel headstock with tungsten carbide wear blades rotating against a stationary alloy steel shearplate with a hardness of 50-55 HRC. The size of the holes in the shearplate may be specified to suit the application. The cutters can be replaced without disturbing the mechanical seal. The seal will rotate in an oil bath to ensure adequate cooling and lubrication which have a sealing rings of differing grades of tungsten carbide.
