There are many other configurations available. For other available options, see the RZL-Series Rotary Lobe Pump Engineered Product Reference Guide 

The JRZL Series are designed to provide complete access of the CIP solutions to all product contact surfaces. All of the pumps are certified with EHEDG and 3A standards and can be cleaned completely through in-line CIP.
Use the following guidelines when designing and installing the CIP system to ensure successful cleaning:

• Ensure that the velocity rate of CIP solutions is adequate to clean the entire circuit. For most applications, a velocity of 5 ft/sec (1.5M/sec) is sufficient. For the CIP solution to achieve the proper velocity, the pump drive must have enough speed range and horsepower. The required inlet pressure also must be satisfied. If the pump does not supply enough CIP solution velocity, a separate CIP supply pump with an installed bypass may be used.
• Ensure that a differential pressure is created across the pump. Differential pressure will push CIP solutions through close-clearance areas of the pump, resulting in better cleaning action. The high pressure side may be either the inlet or outlet side. 30 PSI (2 bar) differential pressure is adequate for most applications.
• The pump must be operated during CIP to increase turbulence and cleaning action within the pump. If complete draining is required, the pump must be in the side mount position.
