WebFeb 8, 2024 · Let’s examine the ideal work cycle of an alternating volumetric pump, without any leaks of any kind inside the pump. Ideal work cycle: Phase 1-2: the fluid is drawn inside the chamber. Phase 2-3: there is an instantaneous compression. Phase 3-4: the fluid is pushed through the delivery duct. WebDec 8, 2024 · When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. All pumps may be classified as either positive-displacement or non-positive-displacement. WebFeb 4, 2024 · Volumetric pumps (Figure 1), sometimes referred to as large volume pumps (LVPs), are the preferred choice for medium and high flow rates and large volume intravenous or enteral infusions. They use a pumping action (typically linear or rotary peristaltic) to pump fluid into the patient under pressure and resistance. phitec electronic
