LTM-Mix Progressing Cavity Hopper Pumps
The LTM-Mix SERIES progressing cavity hopper pumps are the result of continuous improvement of the LTM-Series progressing cavity pump with hopper and high-efficiency infeed screw. They are particularly suitable for pumping high viscosity non-flowing products, with or without suspended solids, including abrasive and non-friable products that tend to form bridges.
By minimising aeration and agitation of fluids, they ensure the gentle product conveyance without altering their organoleptic characteristics.
Wear parts can be easily replaced on site.
The LTM-Mix SERIES progressing cavity hopper pumps have a hopper design that allows easy entry of product into the pump; they are also equipped with an oversized infeed screw at high efficiency and profile to transfer sludge with high concentrations of solids that hasn’t the tendency to make bridge; the arragement is able sometimes to replace the bridgebreaker device.
This particular type of pump has a side feeding port fixed in an optimal position to the hopper that allows optimal mixing of the substrates.
Process connections can use different international standards (EN, DIN, ANSI, GAS and others), or they can have a special design.
They can also be supplied in different types of materials (e.g. CAST IRON, STAINLESS STEEL and others) depending on application contexts.
The LTM-Mix SERIES progressing cavity hopper pumps achieve flow rates up to 180 m³/h and pressures up to 24 bar.
They can also be supplied in a CUSTOM TM-Mix Series as progressive cavity hopper pumps, i.e. with independent bearing support, providing flow rates up to 260 m³/h and pressures up to 40 bar.
Side feeding port
Low rotational speed
Customised executions according to request
The rotor is available in many materials depending on the application: carbon steel with thick chrome plating, AISI 304 (1.4301) stainless steel, AISI 316 (1.4401) stainless steel and others on request. In addition, ‘standard pitch’ or ‘long pitch’ geometry is possible.
The stator is made of vulcanised rubber inside a steel tube, with integral seals on both sides in a variety elastomer (NBR, HNBR, EDPM, FPM and more on request). It is possible to have the stator inlet with hopper-shaped opening for improved feed of the product into the pumping part.
The coupling shaft with a special high-efficiency, high-profile pre-feeding screw for transmitting motion from the drive to the rotor can be made with different types of joints to suit various applications.
The pump housing is designed with a large hopper for optimal loading. There is a removable body with inspection/feeding opening before the stator for easy cleaning or maintenance; in addition, the hopper can be internally coated for optimal protection against abrasion and corrosion (optional).
Different types of process connections are available according to international standards (EN, DIN, ANSI, GAS and others) or in special designs. Different types of materials (e.g. CAST IRON, STAINLESS STEEL and others) are possible depending on application contexts.
There are various types of seals:
The drive is directly flanged to the pump support lantern, resulting in compact dimensions, low total weight, easy maintenance and economic advantages.
The TM-Mix SERIES progressive cavity pumps design, equipped with an independent bearing support, allows coupling with any type of drive via a flexible coupling.
