Harvest 3 Pump - High-End Digital Pump for Complex and Bariatric Care.
- Four Selectable Cycle Times for Clinical Customisation - the Harvest 3 provides cycle time options of 10, 15, 20, and 25 minutes, allowing the alternating cycle to be matched to the individual resident's pressure injury risk, skin condition, and tolerance of positional change; shorter cycle times offload each body zone more frequently and are indicated for residents at very high risk or with existing pressure injuries; longer cycle times are appropriate for residents who find frequent cell movement disruptive to sleep and where risk level permits a less frequent cycle without compromising tissue reperfusion.
- Static and Maxi-Firm Modes for Transfer and Wound Care - static mode maintains all cells at a consistent inflation state for periods when the alternating cycle is not required, such as during medical procedures or wound care assessments; maxi-firm mode inflates all cells to maximum firmness, providing a stable surface for repositioning, transfer, and manual handling manoeuvres where a firm base under the resident is required for carer safety per MHOR 1992; maxi-firm is also used to confirm correct cell inflation during deployment checks.
- Required for All Harvest Bariatric Mattresses - the Harvest 3 is the only pump in the Harvest range compatible with the Hampton Extra (317kg) and Duke Extra 2.0 (317kg) bariatric mattresses; these 1200mm systems require the higher airflow and pressure output of the Harvest 3 to maintain correct cell inflation across the wider cell array under bariatric load; use of any other pump with these mattresses is outside the validated clinical specification and must not occur; the pump-to-mattress pairing must be documented in the equipment register.
- Pressure Range 30-70mmHg - EN60601-1 Certified - 3.5kg - the 30-70mmHg pressure range covers the full bariatric and complex clinical therapy requirement; the LED display provides clear operational feedback; the lockout function prevents unauthorised setting changes; visual and audible alarms cover low pressure and power failure; 3.5kg and 340 x 125 x 220mm; voltage 230v/50Hz, fuse T1A 250v; EN60601-1:2006 and A11:2011 certified.
Harvest 3 Pump - High-End Digital - 4 Cycle Times - Bariatric Compatible - All Harvest Mattresses
The Harvest 3 is the most advanced pump in the Harvest Healthcare range, providing four selectable cycle times (10, 15, 20, and 25 minutes), static and maxi-firm modes, and the airflow performance required for bariatric 1200mm mattress systems. It is the sole compatible pump for the Hampton Extra and Duke Extra 2.0 bariatric mattresses. The 30-70mmHg pressure range covers standard and bariatric clinical requirements. LED display, lockout, and audible and visual alarms are standard. EN60601-1:2006 and A11:2011 certified. 3.5kg; 340 x 125 x 220mm.

Regulatory Compliance
The Harvest 3 meets EN60601-1:2006 and A11:2011 medical electrical equipment safety standards. As the powered component of a Class IIa active medical device system under MDR 2017/745, the pump and mattress must be documented together in the equipment register with SWL verified before deployment per MHOR 1992. For bariatric mattresses the Harvest 3 is the validated pump and no alternative may be used; the serial number of both pump and mattress must be recorded in the equipment register. Cycle time selection must be documented in the resident's pressure care plan with the clinical rationale recorded. Lockout must be engaged after calibration. Alarm functionality must be tested at each deployment and the test recorded for CQC Regulation 12 compliance.
Frequently Asked Questions
How is the correct cycle time selected for a specific resident, and can it be changed during the care episode?
Cycle time selection is a clinical decision made by the prescribing nurse or therapist based on the resident's Waterlow or Braden pressure risk score, the presence and category of any existing pressure injuries, and the resident's tolerance of positional movement during the night. A 10-minute cycle offloads each body zone six times per hour and is indicated for residents at very high risk or those managing existing stage 3 or 4 injuries where maximum dynamic offloading is required. Longer cycle times of 15, 20, or 25 minutes reduce cycle frequency and are appropriate for residents at lower risk levels or for those in whom the 10-minute cycle causes sleep disruption that itself increases pressure risk through reduced mobility and skin perfusion during the night. The selected cycle time must be documented in the care plan with the clinical rationale. Cycle time may be reviewed and adjusted at each reassessment if the resident's risk profile or sleep pattern changes; the lockout must be disengaged by the authorised clinician for adjustment and re-engaged after.
What is maxi-firm mode and when should it be used?
Maxi-firm mode inflates all air cells in the connected mattress simultaneously to the maximum firmness setting, converting the mattress surface from a soft therapeutic surface to a firm, stable platform. It is used in three main clinical situations. First, during resident transfer or repositioning from the bed when a firm base under the resident is needed for the transferring carers to work safely per MHOR 1992 manual handling principles; a soft alternating surface increases the physical effort of a pivot or hoist transfer. Second, during wound assessment or dressing application where the clinician needs the resident to be stable on a firm surface rather than moving with the alternating cycle. Third, during deployment checks when the nurse is confirming that all cells are inflating to the correct firmness before the mattress is placed into clinical service. Maxi-firm must be disengaged and the therapy mode restored to alternating or the appropriate selected mode after the procedure is complete; leaving the pump in maxi-firm mode removes the pressure redistribution function and must not be used for extended periods.
