Frequently Asked Questions
What is a sanitary positive displacement pump?
A sanitary positive displacement (PD) pump moves fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. The pumping action is cyclic and can be driven by pistons, screws, gears, rollers, diaphragms, or vanes.
Although there are quite a few pump options, the majority can be placed into two categories: reciprocating and rotary.
A Reciprocating Positive Displacement pump works by the cyclical strokes of either a piston, plunger, or diaphragm. Rotary positive displacement pumps use the continuous motion of gears to move fluids, rather than the backwards and forwards motion of reciprocating pumps. The rotating element develops a liquid seal with the pump casing and creates suction at the pump inlet. Fluid is drawn into the pump and then enclosed within the teeth of its rotating cogs or gears and transferred to the discharge. The simplest example of a rotary positive displacement pump is the gear pump.
How often do pumps need maintenance?
Hygienic pumps require a maintenance frequency that is based on application demands, product characteristics, and sanitation protocols. In food processing environments, daily clean-out-of-place (COP) or clean-in-place (CIP) procedures are standard, with deeper preventive maintenance typically performed weekly, monthly, or quarterly. Unibloc® hygienic pumps feature QuickStrip® technology that transforms maintenance on lobe pumps from a lengthy procedure into a rapid 20-minute task.
- The pumps feature tool-free disassembly and minimized parts to simplify maintenance. Pump seals are front-loaded and easily accessible, making seal replacement a snap.
- Parts are designed for one-way re-assembly. This eliminates worker errors that could lead to hygienic failures or foreign objects.
- When it comes to AODD pumps, only UHT offers the Flotronic®One-Nut® design that slashes maintenance from hours to minutes. This innovation eliminates extra pipework and enables a worker to access the pump internals by removing one large nut.
Industry standards and regulations mandate rigorous sanitation. With Unibloc Hygienic Technologies’ hygienic pumps, your team spends less time cleaning while maintaining the strict hygienic standards your operation demands.
What is preventive maintenance for pumps?
Preventive maintenance for hygienic pumps involves scheduled inspections, cleaning, and component replacement. Regular preventive maintenance extends pump life, reduces emergency repairs, and prevents unexpected downtime that costs thousands per hour. Inspections include checking seals, examining wear components, verifying proper clearances, and ensuring all product-contact surfaces meet hygienic standards.
Unibloc® Hygienic Technologies’ hygienic lobe pumps with QuickStrip® technology make preventive maintenance remarkably efficient. Workers can replace seals without disassembling the rotor housing, preserving critical tolerances and preventing reassembly errors. With fewer parts to inspect and tool-free access, our Unibloc hygienic pumps transform preventive maintenance from a dreaded task into a quick, routine procedure that keeps your operation running safely and efficiently.
What is the maintenance schedule/cost for a pump?
Maintenance schedules for hygienic pumps vary by application intensity, but typically they include daily sanitation, weekly inspections, and quarterly preventive service. Costs accumulate through labor hours, replacement parts, and production downtime—making efficient maintenance essential for controlling total cost of ownership.
Unibloc® Hygienic Technologies’ hygienic pumps dramatically reduce these expenses through intelligent design. The Unibloc QuickStrip® technology cuts maintenance time by up to 67%, meaning a 20-minute procedure instead of an hour. This time savings translates directly to labor cost reductions and faster return to production. It’s a similar story with our Flotronic® AODD+™ pumps, which can be disassembled, cleaned, and returned to service in 15 minutes versus 2 hours for traditional AODD pumps. It’s proven: our hygienic pumps deliver lower operating costs and better ROI over their lifespan.
