Designed for extreme abrasive fluid transfers with up to 80% solid content, our heavy-duty hose pumps feature zero leakage, unmatched wear and clog resistance, powerful self-priming, and minimalist maintenance. Engineered for critical applications in mining slurries, lithium battery processing, fine chemicals, and water treatment industries.
As it is air-driven, it inherently eliminates the risk of explosions caused by static electricity accumulation or electrical sparks, making it the preferred choice for the safe transfer of fluids in flammable or explosive environments.
Characterized by a simple structural design and exceptional sealing integrity, which significantly reduces the frequency of maintenance requirements.
Utilizing a positive displacement operating principle, the pump can run dry without fluid flow—without sustaining damage—thereby eliminating the need for complex monitoring equipment.
Relies on the reciprocating displacement of diaphragms—rather than high-speed rotating impellers—to transfer fluids, thereby significantly minimizing mechanical agitation and shear-induced degradation of the fluid material.
Features a large-channel valve ball design that reduces flow resistance and accommodates the passage of larger solid particles; diaphragm materials can be customized to suit specific media for corrosion resistance, enabling the effortless pumping of high-viscosity, corrosive, and solid-laden liquids.

A paint manufacturing plant—a partner of Mudisen—operates a filling line where the viscosity of the conveyed base material consistently fluctuates between 4,500 and 5,000 cps throughout the year. The original process utilized a traditional rotary gear pump; however, under the prolonged influence of shear stress, not only did the material flow rate exhibit pulsation, but the elbows within the system’s piping also became highly prone to forming “dead zones” where ink residue would accumulate—deposits that proved extremely difficult to remove.
First, maintenance costs.whenever product batches were switched or colors were changed, the workshop maintenance team was compelled to perform a deep, physical disassembly and cleaning of the equipment, as residual material could not be effectively drained via gravity alone. This process incurred substantial on-site maintenance costs.
Second, Low efficiency.according to the plant’s operations and maintenance logs from the previous year, a single instance of pipe unclogging and pump disassembly/cleaning typically consumed an average of one full 8-hour shift. Such high-frequency, unplanned downtime severely eroded the production line’s effective operational efficiency.
For shear-sensitive fluids with a viscosity exceeding 3,000 cps, simply increasing the pump’s motor output power often proves counterproductive. During the initial stages of process design, prioritizing the selection of a reciprocating pumping system—characterized by large flow channels and low shear forces—is the key to effectively balancing production throughput with long-term maintenance costs.

Such high-frequency, unplanned downtime severely eroded the production line’s effective operational efficiency.
The plant replaced its original system with a Mudisen Model BFQ-40 Stainless Steel Air-Operated Double Diaphragm (AODD) Pump. The following targeted optimizations were implemented to address the existing issues:
Elimination of Inner-Wall Adhesion: The standard nitrile rubber components were abandoned; instead, both the valve balls and diaphragms—the primary fluid-contacting surfaces—were specifically fabricated from PTFE (Polytetrafluoroethylene). The inherently low surface tension characteristics of PTFE significantly reduced the adhesion rate of the high-viscosity medium at a fundamental physical level.
Introduction of CIP Compatibility: Utilizing skid-mounted flanged connections, the new system allows for Clean-In-Place (CIP) procedures without requiring complete disassembly. By leveraging the volumetric, reciprocating flushing action inherent to the pneumatic pump itself, injecting a small quantity of cleaning solvent is sufficient to achieve rapid self-cleaning of the internal fluid channels.
Following 12 consecutive months of operation with the upgraded system, an analysis of the on-site feedback data revealed the following results:
1. The flushing time required during batch changeovers plummeted from the original 8 hours to approximately 15 to 20 minutes.
2. The failure rate associated with pump chamber clogging was effectively reduced to zero. Over the course of the year, this effort cumulatively recovered nearly 400 hours of unproductive downtime for the workshop.
For shear-sensitive fluids with a viscosity exceeding 3,000 cps, simply increasing the pump’s motor output power often proves counterproductive. During the initial stages of process design, prioritizing the selection of a reciprocating pumping system—characterized by large flow channels and low shear forces—is the key to effectively balancing production throughput with long-term maintenance costs.
A standard AODD pump can efficiently handle fluids up to 5,000 - 10,000 cps. With a gravity-fed setup and enlarged piping, it can pump semi-fluids up to 20,000 cps.
Engineering Tip: Because AODD pumps are positive displacement pumps, they handle high-viscosity materials (like inks, resins, or sludge) with low shear. However, keep in mind that as viscosity increases, the actual flow rate will decrease compared to water testing data. We always recommend sizing up the pump by at least 20% for fluids over 3,000 cps
No, it will not cause immediate damage. Unlike centrifugal pumps, AODD pumps have no rotary seals or electrical motors that rely on the pumped fluid for cooling.
Field Advice: While dry running during priming or tank-emptying is completely safe, we strongly advise against leaving the pump running dry continuously for hours. High-frequency dry cycling accelerates the mechanical fatigue of the diaphragms and wastes valuable compressed air.
For fluids that are both highly corrosive and abrasive, the best solution is a two-piece configuration: a PTFE primary diaphragm backed by a Santoprene rubber diaphragm.
Detailed Breakdown: PTFE (Teflon) offers unbeatable chemical inertness but lacks mechanical elasticity, making it vulnerable to sharp solid particles. By adding a Santoprene backup web, the PTFE handles the chemical attack while the rubber absorbs the mechanical stress.

This is a normal physical reaction caused by moisture in your compressed air line, not a pump defect. As highly compressed air expands and exhausts through the muffler, it absorbs heat rapidly, causing trapped water vapor to freeze.
How to Fix: The most effective fix is installing a Filter-Regulator-Lubricator (FRL) unit or an air dryer on your air supply line to reduce the dew point. Alternatively, slightly reducing the air inlet pressure can slow down the icing process.
The daily routine requires only two checks: air supply quality and bolt tightness. The primary wear parts are the diaphragms, valve balls, and valve seats.
Maintenance Focus: Because AODD pumps generate reciprocating vibrations, manifold bolts may loosen over time, especially if water hammer occurs in your piping. Re-torquing the external bolts monthly ensures a leak-free seal. Keeping y
