1 J anus Pumps - Axial Piston Totally oil free, clean and completely safe for people, processes and products. As a result of employing advanced materials, high velocity and loaded sliding surfaces can operate effectively with water as their only coolant/lubricant. The potential for cross contamination of the system fluid or the lubricating oil is removed. The result is an exceptionally small light weight product. Each bearing employs a hard/soft interface that minimises vibration and ensures a low noise and high efficiency operation. Manufactured in 316 stainless steel as standard the product offers excellent resistance to corrosive fluids. The materials utilised internally can be selected to suit the most appropriate combinations for not just tap water but also sea water and various other fluids. Minimal pulsation is experienced with these units due to the multiple piston design and the high operational speeds. Accurate flow metering is simply achieved with the control of the output shaft speed. ASSEMBLY ORDERING CODE NOTE: Variable Pumps are only available as P60 and P Circuit Symbols.

2 Janus CYLINDERS Based on a tie bar design the range of cylinders offer durable construction with high degree of corrosion resistance in comparison to welded designs. The maximum speed of operation is dependant upon the selected material of construction and sealing technique. The materials are selected with respect to the application, duty cycle and fluid. Standard are 316 and high grade engineering polymer, an additional ceramic coating can be applied for extreme environments and duty cycles. The range ensures an appropriate life with low maintenance at the most cost effective solution is applied. ASSEMBLY ORDERING CODE Circuit Symbols. NOTE: Special Cylinders are available upon request.

As a result of employing advanced materials, high velocity and loaded sliding surfaces can operate effectively with water as their only coolant/lubricant. The potential for cross contamination of the system fluid or the lubricating oil is removed. The result is an exceptionally small light weight product. Each bearing employs a hard/soft interface that minimises vibration and ensures a low noise and high efficiency operation. Manufactured in 316 stainless steel as standard the product offers excellent resistance to corrosive fluids. The materials utilised internally can be selected to suit the most appropriate combinations for not just tap water but also sea water and various other fluids. Driven direct by a 4 pole synchronous motor the output flow of the pump can be varied between zero and maximum displacement controlled by, electrical, hydraulic or Mechanical means. Proposed Forms of Control Electronic- By a proportional solenoid in either closed or open loop configurations, see controllers data sheet for further information. Hydraulic- Constant pressure control, the output of the pump will be matched to the system demand by automatically trimming the displacement as a function of the pre set pressure by an integral relief valve. Load sensing control, the output will be trimmed to offer the flow required by actuator making it a very Efficient form of control. Mechanical- By a manual hand wheel. Motor Pump Assemblies A standard range of bell housing and couplings are available for connecting the pumps to the B5 electric motor flange. The pumps are not capable of operating with induced axial or radial loads on the input shaft. Always adopt the use of a 3 part Gear style coupling where possible. If the drive shaft/spigot location is within 0.05mm concentricity direct inline drive assemblies are permissible.

As a result of employing advanced materials, high velocity and loaded sliding surfaces can operate effectively with water as their only coolant/lubricant. The potential for cross contamination of the system fluid or the lubricating oil is removed. The result is an exceptionally small light weight product. Each bearing employs a hard/soft interface that minimises vibration and ensures a low noise and high efficiency operation. Manufactured in A.I.S.I. 316 stainless steel as standard the product offers excellent resistance to corrosive fluids. The materials utilised internally can be selected to suit the most appropriate combinations for not just tap water but also sea water and various other fluids. Minimal pulsation is experienced with these units due to the multiple piston design and the high operational speeds. Accurate flow metering is simply achieved with the control of the output shaft speed. TYPE P1 P6 P15 P30 P60 P180 Displacement cc/rev Max Min Max. RPM unboosted boosted Max Input power (kw) Max. water flow (l/min) Max cont. pressure (bar) Weight (kg) Temperature C max min Pump speeds above 2000rpm are possible under higher boost conditions, consult TWHC Higher temperature operation is possible consult TWHC for details Consult TWHC for antifreeze option and lower temperature conditions Motor Pump Assemblies A standard range of bell housing and couplings are available for connecting the pumps to the B5 electric motor flange. The pumps are not capable of operating with induced axial or radial loads on the output shaft. Always adopt the use of a 3 part Gear style coupling where possible. If the drive shaft/spigot location is within 0.05mm concentricity direct inline drive assemblies are permissible. Temperature The units will generate full performance from 2 C to 50 C. For temperatures below freezing an environmentally friendly antifreeze is available; ask for the glycol data sheet. Operation above 50 C is possible, but the volumetric efficiency of the unit will be affected consult TWHC and specify the maximum operating temperature. Filters All incoming water to the pumps must be pre-filtered to a nominal rating of 10µm (25µm absolute) with a filter element rating of ß10 = 75 or better. Return line filtration is advisable on closed loop systems. High pressure filtration may also be considered. Issue 8.09
