Must Pump

Upgrade your pump with our optional Air-Charged Dampener. Diaphragm pumps naturally create a "pulsing" flow; our dampener smooths this out into a steady stream, which is essential for filtration processes. By removing the surge, you protect your filter media from pressure spikes, ensuring a cleaner finish and longer filter life. This unit is sized for the 3" MB Sanitary Pneumatic Diaphragm Pump. Tri-clamp adapter fittings are included.

MB 3" – Heavy Must Specialist: The industry standard for fermented must, featuring a generous 6.4 mm particle pass that allows seeds, stems, and skins to move freely without the risk of clogging or labor-intensive downtime. Resilient Self-Priming Design: Built to run dry without damage, these pumps are perfect for variable flows and won't fail if your hopper or tank runs empty during a transfer. High-Vacuum Suction Power: Specifically designed to "pull" thick, viscous materials and "dry" solids, providing the necessary lift to move heavy must without the pump stalling or air-locking. Gentle, Low-Shear Transfer: Minimizes vibration and "slugging" through a pneumatic operation that protects the integrity of your juice or wine while extending the lifespan of the internal diaphragms. MB Series Sanitary Diaphragm Pumps Sleek Design. Industrial Strength. Our MB Series Air-Operated Double Diaphragm (AODD) pumps combine a high-polish, sanitary aesthetic with rugged reliability. Featuring a unique stainless steel wrap-around cover that protects the air valve mechanism, these pumps offer a clean, streamlined look that fits perfectly in any modern production facility. Constructed from 304 Stainless Steel with high-performance Super Teflon and Polyether diaphragms, these pumps are engineered for longevity and ease of cleaning. Whether you are moving delicate liquids or solids-laden must, the MB Series delivers consistent, shear-sensitive flow.

By removing the surge, you protect your filter media from pressure spikes, ensuring a cleaner finish and longer filter life. Specialized Winery Applications Moving Must & Solids: For moving fermented must or pomace, the MB 3" is the gold standard due to its 6.4mm solids handling and high volume. While the MB 2" can work for musts where more liquid is present (up to 4.8mm particles) such as higher liquid content crushed grapes as well as doing pump-overs mid ferment. If you're buying the pump with the intent to use it for must, the 3" model significantly reduces the risk of clogging and provides the necessary torque to move heavy skins and seeds without stalling. The MB 1.5" is recommended for wine, juice, or light lees only. Choosing Between 2-inch and 3-inch Choosing the right pump size for your winery—specifically between a 2-inch and a 3-inch unit—usually comes down to how much solids you’re moving and how much you value your sleep during harvest. The 2-Inch Unit: Precision for Liquids The 2-inch pump is your go-to for liquid-heavy transfers and boutique-scale operations. While it can handle crushed grapes, it requires a high liquid-to-solid ratio to stay happy. If your must is "dry" or contains whole berries, a 2-inch pump will often struggle, leading to "slugging"—a rhythmic vibration that wears down your diaphragms prematurely. It’s the perfect choice if 90% of your day involves moving wine or juice rather than thick skins. The 3-Inch Unit: The Must-Have Workhorse When it’s time to move fermented must to the press, the 3-inch model is the industry standard for a reason. It isn’t just about flow rate; it’s about clearance. With a 6.4 mm particle pass, it handles seeds, stems, and skins without breaking a sweat. Its larger diaphragm surface area creates a stronger vacuum, allowing it to "pull" thick, viscous material that would cause a smaller pump to stall or air-lock. Which One Do You Need? Choose the 1.5-Inch if: Your operations are strictly focused on finished wine, juice, or light lees. With a maximum particle pass of 3.2 mm, this size is designed for high-efficiency liquid transfer where solids are minimal or non-existent. It is the most compact and economical choice for general cellar work that doesn’t involve heavy skins or stems. Choose the 2-inch if: You are a small-lot producer primarily moving juice and wine, or if your must is consistently well-crushed and juicy. Choose the 3-Inch if: You are moving heavy fermented reds to the press. It’s far less likely to clog, saving you hours of labor and preventing the dreaded "bridging" at the intake. Regardless of size, diaphragm pumps still need a little lubrication. Keep a "juice reserve" handy to splash into your hopper; it helps the skins slide through the system and keeps your harvest moving smoothly. Pro-Tip: If you are moving must that is particularly "dry," ensure your suction hose is as short and straight as possible. Every foot of hose and every bend adds friction that a diaphragm pump struggles to overcome when there isn't enough liquid to act as a lubricant.   Versatility Beyond the Vineyard While designed with the winery in mind, the MB Series is a workhorse across multiple industries. Their self-priming, seal-less design makes them ideal for: Food & Beverage: Transferring juices, oils, sauces, and dairy products. Cosmetics & Pharma: Handling lotions, creams, and high-purity fluids. Chemical Processing: Moving shear-sensitive or abrasive chemicals. General Industrial: Sump evacuation, drum emptying, and viscous fluid transfer. Note: All MB Series pumps are air-powered and require a standard air compressor for operation. Each unit features integrated one-way check valves to ensure consistent priming and prevent backflow.   Model # Inlet/Outlet (in) Max Flow (GPM) Air Supply (CFM) Solid Size (in) Max Temp (°F) PMP6600 1.5" TC 39.6 23.7 0.1" 248 PMP6601 2.0" TC 99.9 31.8 0.2' 248 PMP6602 3.0" TC 150.0 53.0-70.6 0.3" 248

Highest quality winery pump available with lowest shear value due to the peristaltic design and the low maximum RPM of 75 Use with removable hopper under a destemmer to move destemmed grapes or must Hopper can be removed to use pump for all other pumping applications Two compensation chambers and automatic pressure sensor eliminate pulsing allowing it to be used for filtering - up to 45 psi of pressure.  Perfect for the gentlest transfer of wine throughout the winery Variable Frequency Drive speed control with remote control.  The peristaltic pump is the ultimate high, quality pump for all winery purposes. This pump with removable loading hopper is suitable for use with destemmed grapes and fermented grapes. The loading hopper is also made from stainless steel on casters and features its own motor with mechancial speed control. The level probe in the hopper turns the pump on and off as needed.  With the hopper removed an included second compensation chamber is connected to reduce pulsing, making it suitable for filtering.  The motor is controlled by a variable frequency drive to control the speed and rotation of the pump from 25 RPM to Max. Wireless remote control included as standard. The pump is connected to the grape receiving hopper by DIN fittings which provide the strongest connection.  Included with the package are two adpators to convert from DIN to Tri-Clamp in order to use the pump with Tri-Clamp hose connections.  If you do not plan to use the collection hopper we can quote a lower price without. Without the hopper it is then also possible to provide the pump directly with Tri Clamp fittings welded in place.   Features: 0.55 kw motorized loading hopper with screw supply Pump body in AISI 304 with internal tubing in EPDM Electronic speed variator for speed control from 10 RPM to max 75 RPM; Minimum working RPM is 25 in order to sufficiently cool motor.  Electrical system with emergency stop Automatic filling pressure switch Automatic level probe on hopper turns off both the pump motor and receiving motor. Max Pressure (All Models): 43.5 PSI (3 BAR) 3" tri-clamp connection 220V, 3 Phase Wirelss remote for control up to 50 meters away (150 meters if no walls)
