Moyno 2000 HS System vs. Piston Ram Type Pump
• 2000 HS System offers lower capital investment, lower cost of operation and less maintenance
• Piston pumps are priced between $135,000 and $375,000 – The Moyno 2000 HS System has an estimated selling price of
one-half the cost of an equivalently sized piston pump
• High inefficiencies converting from electrical to hydraulic to mechanical energy
• Sensitive hydraulic systems require frequent adjustments from specially trained technicians
• Costly disposal fees for used hydraulic oil
17
Efficiency of Electrical vs. Hydraulic Drive Systems
• In comparison to electric drives, hydraulic drives require more changes of energy state to accomplish the desired output
• Each change of state creates efficiency losses

Moyno 2000 HS System vs. Piston Ram Type Pump
• Non-pulsating flow of the Moyno® 2000 G4 pump translates into significantly lower operating pressures
• Piston pumps' high discharge pressures require larger pipe diameters and higher rated fittings
• Soft start capability of the 2000 HS System limits the amplitude of peak start-up discharge pressure
• A piston pump's discharge pressure peaks at the beginning of each stroke then falls dramatically upon completion
• Piston ram pump drive components and piping must be sized for continuous pressure spikes

Moyno 2000 HS System vs. Piston Ram Type Pump
• No cumbersome highly sensitive hydraulic systems, valves or ancillary components with the 2000 HS System
• Piston pumps require a complicated array of exposed high pressure hydraulic lines, fittings, valves, accumulators, two valves per cylinder and electronic time sensing instrumentation
• Piston pumps require sensitive hydraulic systems that require frequent adjustments by specially trained technicians
• No oil cooler, oil filtration or oil lines required
26
Moyno 2000 HS Ssytem vs. Piston Ram Type Pump
• Repairs of piston pumps must take place off-site to avoid contamination of internal components
• 2000 HS System requires less floor space• Large cumbersome drive and control system cabinetry
common on piston pumps consumes extra floor space
• Piston ram pumps have limited configurations that reduce installation flexibility
• 2000 HS System consumes less power
27
Moyno 2000 HS System vs. Piston Ram Type Pump
• Piston pumps require a significantly greater amount of power to generate the same flow rate as the highly efficient 2000 HS System
• Significantly quieter operation with the 2000 HS System
• Dual piston pumping action generates high decibel levels
• Slip injection system utilizes an efficient Moyno® Metering Pump to dose fluid
• Slip injection systems common to piston pumps employ expensive high pressure metering pumps
28
Moyno 2000 HS System vs. Belt Conveyor
• 2000 HS System offers lower capital investment, lower cost of operation and less maintenance
• Belt conveyors cost a minimum of $1,000 per linear foot
• Each change in vertical or horizontal direction on a belt conveyor requires a dedicated belt and drive, thus driving the price up to approximately $3,000 per linear foot
• Conveyor belt repair costs are expensive and require frequent maintenance
29
Moyno 2000 HS System vs. Belt Conveyor
• Substantial support or hanger system, housings and service catwalks add to high capital investment
• Belt conveyors require extensive floor space
• Clean, unobtrusive, closed piping system with the 2000 HS System
• Odor is a problem on open conveyors where sludge cake is exposed to the atmosphere
• Spillage results in environmental and safety concerns
• Belt conveyor housings require regular cleaning to remove spillage
30
Moyno 2000 HS System vs. Screw Conveyor
• Lower capital investment, lower cost of operation and less maintenance with the 2000 HS System
• Screw conveyors cost approximately $1,400 per linear foot
• Any change in elevation increases the investment to approximately $2,000 per linear foot
• A separate, costly drive system is necessary whenever a screw conveyor changes direction
• The G4 pump and twin screw feeder have separate drives and each is controlled through a PLC
31
Moyno 2000 HS System vs. Screw Conveyor
• With the 2000 HS System, material moves smoothly through closed piping over great distances without alteration to the system or the need for special accessories
• Screw conveyors require intermediate bearing supports for long lengths
• When distances exceed practical manufacturing sizes, material must transfer to another conveyor in order to reach the discharge end
• Screw conveyors require covers to limit odor and housekeeping
32
Moyno 2000 HS System vs. Screw Conveyor
• 2000 HS System uses genuine Moyno replacement parts delivered off-the-shelf and ready to install in-plant
• Screw conveyors use expensive custom-made screws and troughs that require extended downtime for fabrication and installation
• Superior solids handling ability with 2000 HS System
• Large particles can lodge between the O.D. of the screw and the inside wall of the trough on a screw conveyor causing flow stoppage and consequent downtime for service
33
Testing
• Moyno has extensive experience pumping extremely high solids sludge
• The Moyno 2000 HS System has undergone extensive testing in Moyno's lab and in the field at an Ohio municipal wastewater treatment facility
34
